HDT Vicat Softening Point Apparatus The HDT Vicat softening point apparatus is a testing instrument used to determine the softening point of a material. It is commonly used in the plastics industry to evaluate the heat resistance and thermal stability of polymers.

The apparatus consists of a heating bath, a test specimen holder, and a needle or a flat-ended plunger. The test specimen is placed in the holder and immersed in the heated bath. The temperature is gradually increased at a specified rate, and the needle or plunger is applied to the specimen at regular intervals.
The softening point is determined by observing the point at which the needle or plunger penetrates a specified distance into the specimen. This indicates the temperature at which the material starts to soften and lose its dimensional stability.
The HDT Vicat softening point apparatus is designed to meet international standards, such as ISO 306 and ASTM D1525. It provides accurate and reliable results, allowing manufacturers to assess the suitability of materials for various applications and ensure product quality.
Zhejiang Gas Spring Factory Direct Sales, Support Rod Factory Direct Sales. A gas spring, also known as a gas strut, is a mechanical component used for support, cushioning, and motion control in industrial applications. It is commonly used for height adjustment, angle adjustment, and movement systems. The main components of a gas spring include the pressure cylinder, piston rod, piston, sealing guide sleeve, packing (which may contain inert gas or a mixture of gas and oil), internal control elements, external control elements (for controllable gas springs), and various joints.
The working principle involves filling a sealed pressure cylinder with inert gas or a gas-oil mixture, creating internal pressure that is several times higher than atmospheric pressure. This pressure difference, based on the cross-sectional areas of the piston rod and piston, allows for controlled movement of the piston rod. Unlike traditional mechanical springs, gas springs offer a nearly linear elastic curve, making them more predictable and easier to control.
Gas springs have several advantages over conventional springs. They operate at a relatively slow speed, exhibit minimal variation in dynamic force (typically within a 1:1.2 ratio), and are easy to regulate. However, they do have some disadvantages, such as a larger volume, higher cost, and a shorter lifespan compared to mechanical springs. Standard gas springs usually have a spring constant (X) ranging from 1.2 to 1.4, though other parameters can be customized based on specific requirements and operating conditions.
Due to their versatility, gas springs are also referred to by various names, including support rods, gas supports, angle adjusters, gas bars, and dampers. Based on their structure and function, they come in different types, such as free gas springs, self-locking gas springs, tension gas springs, random gas springs, rotating chair gas springs, gas pressure bars, and shock absorbers.
This product is widely used across multiple industries, including automotive, aerospace, medical equipment, furniture, and machinery manufacturing. Whether it's for lifting mechanisms, adjustable seating, or precision control systems, gas springs play a vital role in enhancing performance and user experience.
