Mounting Press

HM Series

Our HM series Metallographic specimen mounting press is a mechanical/manual machine. The operator can change 4 specification patterns according to the difficult specimens. It is suitable for all Thermosetting Materials. In the operation of machine by rotating the hand‐ wheel of the machine, a coupling of bevel gear is rotated to drive the screw rod which pulls the die in mould. The thermoset plastic granules together with specimen being mounted is formed under heated conditions. During this process the pressure is self-adjusted by a spring fixed inside the machine. A signal light is used to indicate the pressure level. The mounting press is equipped with a PID digital temperature controller to establish real‐time temperature meanwhile, the timer is equipped to realize the semi‐automation of sample–making, while obviously increasing working efficiency. For each specimen mounting, 8‐10 minutes is enough and a mirror-like a specimen can be acquired.

Description

Mounting Press HM Series

Mounting press, also known as a mounting machine or mounting press machine, is a piece of equipment used in the preparation of materials for metallographic analysis or microscopy. It is commonly used in materials science, metallurgy, and quality control laboratories. The primary purpose of a mounting press is to embed a specimen, typically a metal sample, in a hard, transparent plastic resin, often referred to as a mounting medium. This process allows for the examination of the sample’s microstructure under a microscope with high clarity and precision.

Key Features :

Embedding Specimens: The primary function of a mounting press is to embed specimens in a mounting medium. This process involves placing a prepared metal sample into a mold along with the chosen mounting resin.
Heat and Pressure Application: Once the sample and mounting resin are in the mold, the mounting press applies heat and pressure to the assembly. This helps in achieving a solid, bubble-free, and uniform embedding of the specimen in the resin.
Polymerization: Some mounting presses have the capability to control the polymerization process, which is the chemical reaction that solidifies the resin. This ensures that the resin hardens properly around the specimen.
Cooling: After the polymerization process is complete, the mounting press may include a cooling phase to rapidly cool down the embedded sample, ensuring minimal distortion or shrinkage.
Mold Options: Mounting presses often come with various mold sizes and shapes to accommodate different specimen sizes and orientations. These molds can be cylindrical or square, depending on the application.
Temperature and Pressure Control: Precise control of temperature and pressure is essential to achieve consistent and high-quality results. Modern mounting presses often offer digital control for these parameters.
Safety Features: Safety features, such as interlocks and safety shields, are commonly integrated into mounting presses to protect users from hot surfaces and moving parts during operation.
User-Friendly Interface: Many mounting presses have user-friendly interfaces with touchscreens or digital displays, allowing operators to set parameters, monitor the process, and store customized programs for future use.
Compatibility: Mounting presses are designed to work with a variety of mounting resins, which may have different characteristics suited for specific applications.
Quality Control: The embedding process performed by a mounting press is crucial for obtaining accurate and reliable metallographic or microscopic analysis results. These machines contribute to quality control in industries where material properties are critical.
