What Can a Universal Strength Tester Measure and Why Is It Essential for Lab Use?

Do you know what a tensile testing machine is? Let's uncover its mysteries together.


1. What is a tensile testing machine?

A tensile testing machine, also known as a universal testing machine, is like a doctor that gives materials a comprehensive “checkup.” It is mainly used to measure the mechanical properties of various materials, such as plastics, metals, rubber, and textiles. By applying forces such as tensile, compressive, bending, shear, peel, and tear forces to these materials, it can precisely measure important performance indicators such as strength, toughness, and elastic modulus.


In terms of working principle, a tensile testing machine primarily relies on Hooke’s Law and strain measurement principles. Hooke’s Law states that within the elastic range, the force applied to a material is directly proportional to the deformation it undergoes. The strain measurement principle involves calculating the material's various mechanical properties by measuring the minute deformation of the material under force. When a material sample is secured to the tensile testing machine and the force is gradually increased, the sensors on the machine precisely record the force applied to the material and the resulting deformation, thereby determining the material's performance parameters.

A tensile testing machine primarily consists of several key components. First is the drive system, which transmits the motor's power to the loading system. The loading system is responsible for applying force to the material and can precisely control the magnitude and direction of the force applied to the material according to different test requirements. The measurement system uses various sensors, such as force sensors and displacement sensors, to monitor the force applied to the material and the resulting deformation in real time. The control system can precisely control the entire testing process according to pre-set programs, ensuring the accuracy and reliability of the test results.



2I. Classification of Tensile Testing Machines

There are numerous types of tensile testing machines, which can be classified according to different standards.

Based on the level of automation, we can classify them into pointer-type tensile testing machines, digital display tensile testing machines, and computer system tensile testing machines.

Based on the type of control system, they can be categorized into variable frequency system tensile testing machines, servo system tensile testing machines, and other drive type tensile testing machines.

Based on industry and functional characteristics, they can be categorized into metal tensile testing machines, rubber tensile testing machines, plastic tensile testing machines, textile tensile testing machines, paper tensile testing machines, and leather tensile testing machines, among others.

Additionally, they can be categorized based on test materials, temperature, application, and degree of automation. For example, based on test materials, they can be divided into tensile testing machines with metal material fixtures and non-metal material fixtures; based on test temperature, they can be divided into tensile testing machines with room temperature, high-temperature, low-temperature, and high-low temperature fixtures; based on application, they can be divided into tensile fixtures, compression fixtures, bending fixtures, and other application-specific tensile testing machines; based on automation level, they can be divided into manual, pneumatic, electric, and hydraulic fixture tensile testing machines.


3. Application Areas of Tensile Testing Machines

Tensile testing machines have widespread applications across various fields.

In the industrial sector, industries such as manufacturing, metallurgy, petroleum, chemicals, and construction materials all rely on tensile testing machines.

For example, in mechanical manufacturing, tensile testing machines can be used to test the strength and toughness of various mechanical components, ensuring product quality and reliability. In the manufacturing industry, textile factories use tensile testing machines to test the elongation rate of fabrics, ensuring that finished garments do not deform easily when worn.

In the metallurgy industry, tensile testing machines can be used to test the performance of metallic materials such as steel, providing a basis for improving metallurgical processes.

In the petroleum and chemical industries, tensile testing machines can be used to test the material properties of various pipelines, containers, and other equipment, ensuring safe operation under harsh working conditions.

Oil vs. Water Mold Temperature Controller Machine for Rubber Injection Molding

Hengde Company, a renowned enterprise in the industrial temperature control field, has been committed to the research, development, and production of high performance mold temperature controller equipment. Our products, including both water mold temperature controller machines and oil mold temperature controller machines, have been widely used in various plastic and rubber processing industries, providing reliable temperature control solutions for our customers. When it comes to the rubber injection molding process, the choice between an oil mold temperature controller machine and a water mold temperature controller machine is a common concern. In fact, both oil mold temperature controller machines and water mold temperature controller machines belong to the category of mold temperature machines, and the fundamental difference between them lies in the heat transfer media they use. Water mold temperature controller machines use water, while oil mold temperature controller machines use heat conducting oil. In the rubber injection molding process, each has its own advantages and disadvantages, and the choice of which equipment to use mainly depends on specific production requirements and conditions.

Mold Temperature Controller For Rubber Injection Machine

 

1.Operating Temperature

Oil mold temperature controller machine: Oil mold temperature controller machines can provide a much higher operating temperature, usually reaching 300℃, 350℃ or even higher. For some rubber materials that require high temperature injection molding, such as certain special type rubbers, oil mold temperature controller machines can meet their processing temperature requirements. This ensures that the rubber materials are fully melted, achieving good fluidity, which is convenient for filling the mold cavity and thus obtaining high quality rubber products.

 

Water mold temperature controller machine: The operating temperature of water mold temperature controller machines is generally below 180℃. If the temperature required for the rubber injection molding process is within this range, water mold temperature controller machines can be applied. For the injection molding of ordinary rubber materials, water mold temperature controller machines can provide stable temperature control to ensure product quality.

 

For example, a customer's PP material has a molding temperature range of 160℃ - 220℃, and the mold temperature needs to be kept constant within this range during the molding process.Since the heating range exceeds 180℃, a water mold temperature controller machine is unsuitable. An oil mold temperature controller machine is recommended.

 

2.Heat Transfer Efficiency

Oil mold temperature controller Machine: The specific heat capacity of oil is relatively smaller than that of water. However, at high temperatures, the heat transfer performance of oil is stable, and it will not generate a large amount of steam like water at high temperatures, which could lead to pressure problems. In injection molding processes that require rapid heating or cooling, oil mold temperature controller machines can transfer heat to the mold more quickly, improving production efficiency.

 

Water mold temperature controller machine: Water has a large specific heat capacity. Under the same temperature change, it can absorb or release more heat. In injection molding processes with a small temperature variation range, water mold temperature controller machines can utilize this characteristic to control the mold temperature more stably, with relatively small temperature fluctuations.

 

3.Safety

Oil mold temperature controller machine: Oil is a flammable substance. When using an oil mold temperature controller machine, fire prevention measures need to be taken. Open flames should be avoided around the equipment, and corresponding fire extinguishing equipment should be equipped. At the same time, the sealing requirements of oil mold temperature controller machines are relatively high to prevent oil leakage from triggering safety accidents.

 

Water mold temperature controller machine: Water is non flammable. Compared with oil - temperature machines, water mold temperature controller machines are safer. In some production environments with strict fire prevention requirements, water mold temperature controller machines are a more suitable choice.

 

4.Cost

Oil mold temperature controller machine: The price of oil is relatively high, and it needs to be replaced after a period of use, increasing the operating cost. In addition, the maintenance cost of oil temperature machines is also relatively high. The heating system, circulation system, and other components need to be regularly inspected and maintained to ensure the normal operation of the equipment.

 

Water mold temperature controller machine: Water is low cost and easily accessible. The maintenance of water mold temperature controller machines is relatively simple, mainly inspecting and maintaining components such as pipelines and water pumps, and the operating cost is low.

 

Mold Temperature Controller

In summary, if the rubber injection molding process requires high temperatures, has requirements for heating speed, and can meet the safe use conditions of oil temperature machines, then an oil mold temperature controller machine may be more suitable. Because heat conducting oil is used as the heat transfer medium, it has excellent thermal stability, and the temperature control range is from room temperature to 400℃, which can meet the heating needs of various high temperature materials. If the molding temperature is within the operating temperature range of a water mold temperature controller machine, and there are strict cost  control requirements while pursuing high safety, a water mold temperature controller machine is a better choice. Because the temperature control range of a water mold temperature controller machine is from room temperature to 180℃, and it uses clean water resources as the heat transfer medium, which is clean, environmentally friendly, and pollution free. Coupled with the excellent heat conduction performance of water, it can heat the mold very quickly. Equipped with a PID ± 1℃ intelligent temperature controller, it can fully meet the requirements of the injection molding process.

 

 

In actual injection molding process production, since the heat required temperature of most injection molding materials is below 180℃, many manufacturers choose to use water mold temperature controller machines as auxiliary temperature control equipment for the injection molding process, and relatively fewer use oil mold temperature controller machines. Overall, whether to choose an oil mold temperature controller machine or a water mold temperature controller machine should be compared according to the actual situation. Hengde Company always provides professional advice and high quality products to help customers make the most suitable choice for their production processes.

However, they are generally less energy-efficient than water-cooled chillers and can be noisy, particularly when operating at high capacities.

 

Water-cooled chillers, on the other hand, are designed for applications that require high cooling capacities and maximum energy efficiency. They use water as a cooling medium to transfer heat from the refrigerant to the environment, typically through a cooling tower or a closed-loop water system. Water-cooled chillers are more efficient than air-cooled chillers, but they require a more complex installation and maintenance setup, including a dedicated water supply and regular water treatment.

 

Screw chillers are known for their high efficiency, reliability, and ability to handle large cooling capacities. They utilize a screw compressor to compress the refrigerant and generate cooling, and they can adjust their capacity to match the cooling load requirements of the application. Screw chillers are relatively compact and operate quietly, making them suitable for a variety of industrial applications.

 

Shell and tube chillers are characterized by their high heat transfer efficiency and versatility. They consist of a cylindrical shell containing a bundle of tubes, and they can be used with a variety of refrigerants and cooling fluids. Shell and tube chillers are relatively easy to clean and maintain, but they can be more expensive than other types of chillers, particularly for smaller cooling capacities.

 

Consider your specific cooling requirements, installation constraints, budget, and maintenance preferences when evaluating chiller types. It may also be helpful to consult with a chiller manufacturer or supplier to get their expert advice and recommendations.

Step 3: Consider Energy Efficiency

Energy efficiency is an important consideration when choosing an industrial chiller, as it can have a significant impact on your operating costs over the long term. Look for chillers that are designed to be energy-efficient, with features such as variable speed drives, high-efficiency compressors, and advanced control systems. These features can help you reduce energy consumption and lower your utility bills.

 

You can also look for chillers that have been certified by energy efficiency organizations, such as the Energy Star program in the United States. Energy Star-certified chillers meet strict energy efficiency guidelines and can provide significant energy savings compared to non-certified models.

Step 4: Evaluate Maintenance Requirements

Regular maintenance is essential to ensure the optimal performance and longevity of your industrial chiller. When choosing a chiller, consider the maintenance requirements and costs associated with each type. Some chillers may require more frequent maintenance and servicing than others, and this can impact your operating costs and downtime.

 

Look for chillers that are designed to be easy to maintain, with features such as accessible components, modular designs, and self-diagnostic capabilities. These features can make it easier to perform routine maintenance tasks, such as lubricating the compressor, replacing the filters, and checking the refrigerant levels.

 

It's also important to consider the availability of spare parts and the quality of customer support provided by the chiller manufacturer or supplier. Choose a manufacturer or supplier that has a reputation for providing reliable products and excellent customer service, and that offers a comprehensive warranty and maintenance program.

Step 5: Compare Prices and Quotes

Once you have narrowed down your options to a few chiller models that meet your requirements, the next step is to compare prices and quotes from different manufacturers and suppliers. Be sure to compare the total cost of ownership, including the purchase price, installation costs, operating costs, and maintenance costs, rather than just the initial purchase price.

 

It's also important to consider the reputation and reliability of the manufacturer or supplier, as well as the quality of their products and services. Look for manufacturers and suppliers that have a proven track record of providing high-quality chillers and excellent customer support.

 

In conclusion, choosing the right industrial chiller requires careful consideration of your cooling requirements, chiller types, energy efficiency, maintenance requirements, and budget. By following these steps and doing your research, you can make an informed decision and select the chiller that best meets your needs and provides the most value for your investment.

1. Clarify Core Cooling Parameters

 

Cooling Capacity Matching

Calculate the required cooling capacity (in kW or HP) based on the heat dissipation needs of the equipment or process to avoid "overcapacity" or insufficient cooling.

For example: Small laser marking machines require 5-10HP units, while large injection molding machines may need 50HP or more.

Reference formula: Cooling capacity (kW) = Equipment power (kW) × Heat dissipation coefficient (usually 0.6-0.8, adjusted by equipment type).

 

Temperature Control Precision

High-precision scenarios (e.g., medical equipment, semiconductor crystal growth) require models with ±0.5℃ accuracy or better.

General industrial scenarios (e.g., plastic molding) can suffice with ±1-2℃ precision.

 

2. Adapt to Environmental Conditions

 

Ambient Temperature

For high-temperature environments (e.g., tropical regions, workshops with multiple heat sources), choose "high-temperature resistant" units that operate stably at 40-45℃.

For low-temperature environments (e.g., outdoor cold zones), select models with "low-temperature startup" or "anti-freeze protection" functions.

 

Installation Space and Ventilation

In confined spaces (e.g., laboratories, rooftops), prioritize compact, modular units. Ensure the cooling fan has sufficient ventilation space (at least 1.5 meters from obstacles).

Outdoor installations require rainproof and dustproof designs; coastal areas need stainless steel models resistant to salt spray corrosion.

 

Special Environmental Requirements

Explosive environments (e.g., chemical workshops, oil and gas industries) require explosion-proof units with ATEX or IECEx certification.

Clean environments (e.g., food processing, pharmaceuticals) need fully closed circulation and leak-proof designs to avoid material contamination.

 

3. Align with Application Scenario Characteristics

 

Industrial Manufacturing

Injection Molding/Extrusion: Choose units with "load fluctuation adaptation" (to handle transient heat changes during mold opening/closing). Screw compressors are recommended for durability.
 
Welding/Cutting Equipment: For short-term, high-frequency heat dissipation, select "rapid cooling" models with buffer tanks to prevent temperature fluctuations.

 

Precision Instruments

Laser Equipment: Lasers are temperature-sensitive; choose "low-vibration, low-noise" models (to avoid disrupting optical stability) with flow control precision ≤±2L/min.

Medical Equipment (e.g., MRI, CT): Requires medical certifications (e.g., ISO 13485), oil-free compressors (to prevent contamination), and 24/7 continuous operation capability.

 

Commercial and Special Scenarios

Small Ice Rinks/Cold Storage: Select low-temperature units (outlet temperature 0-5℃) with high-efficiency heat exchangers.

Data Centers: Need redundant design (N+1 backup), remote monitoring, and intelligent load adjustment (to match server heat fluctuations).

Introduction to Different Types of Crushers and Their Applications

In various fields such as industrial production and resource recycling, crushers play a crucial role. Different types of crushers are suitable for different materials and production requirements. Here are several common types of crushers introduced to you.

Screw Chillers Efficient Industrial Cooling Solutions for Modern Businesses

Introduction​
​In today's fast-paced industrial landscape, maintaining optimal temperature control is crucial for the smooth operation of various manufacturing processes, data centers, and commercial facilities. Screw chillers have emerged as a leading solution for reliable and energy-efficient cooling, offering robust performance and adaptability to diverse cooling demands. This article explores the working principles, key advantages, applications, and selection criteria of screw chillers, helping businesses make informed decisions for their cooling systems.
​
What Are Screw Chillers?​
A screw chiller is a type of industrial refrigeration system that uses a screw compressor to cool and circulate refrigerant, providing chilled water or air to maintain the desired temperature in a facility. The core component is the twin-screw compressor, which consists of two intermeshing helical rotors (a male rotor with convex threads and a female rotor with concave threads). These rotors compress the refrigerant vapor, raising its pressure and temperature, which is then condensed into a liquid in the condenser. The liquid refrigerant is expanded through an expansion valve, cooling it down before entering the evaporator, where it absorbs heat from the environment, completing the refrigeration cycle.​
Key Components​
  • Screw Compressor: The heart of the chiller, responsible for compressing the refrigerant.​
  • Condenser: Converts high-pressure, high-temperature refrigerant vapor into a liquid by releasing heat.​
