Cold Mounting Molds
Specialized molding tool for metallographic sample cold mounting process, made of high-strength plastic or aluminum alloy with smooth inner wall and high dimensional accuracy. Used for forming standard cylindrical mounting blocks at room temperature without heating or pressure, compatible with epoxy and acrylic cold mounting resins, easy demolding and reusable for long term.
Cold Mounting Mold is a essential dedicated fixture for room-temperature metallographic sample cold mounting operations, designed to match with two-component epoxy and acrylic cold mounting resins perfectly. Unlike hot mounting molds that need to withstand high temperature and high pressure, this mold is specially developed for room-temperature curing scenarios, focusing on smooth demolding, stable molding size and long-term reusability, solving the problems of resin bonding, difficult demolding and uneven mounting block size in manual cold mounting.
It is divided into two mainstream high-quality types: high-hardness engineering plastic mold and lightweight aluminum alloy mold, both adopting precision processing technology to ensure uniform inner wall thickness, flat bottom and strict cylindrical dimensional tolerance, forming standard, neat and smooth mounting blocks after resin curing. The mold features simple split or integrated structure, easy to assemble, disassemble and clean, suitable for fixing and encapsulating various heat-sensitive, fragile, thin, small and irregular samples that are not suitable for hot mounting, widely used in metallographic laboratories, material testing centers, scientific research institutions and teaching labs for daily small-batch sample mounting work.
2. Core Advantages
-
High-Precision Molding Size: Adopts precision machining and molding process, with strict control of inner diameter and height tolerance, ensuring each cured mounting block is standard in size, uniform in shape and flat in surface, laying a solid foundation for subsequent grinding and polishing operations.
-
Smooth Inner Wall for Effortless Demolding: The inner wall and bottom are polished to a mirror-smooth finish, with no burrs, grooves or uneven areas, effectively preventing cold mounting resin from bonding and adhering to the mold inner wall. Combined with special metallographic release agent, it can realize intact and quick demolding without damaging the mounting block or sample edges.
-
Two Material Options for Flexible Selection: Engineering plastic mold features lightweight, low cost, corrosion-resistant and insulating properties, suitable for daily general cold mounting and disposable temporary use; aluminum alloy mold has higher rigidity, no deformation, better heat dissipation and ultra-long service life, ideal for long-term repeated high-frequency use.
-
Strong Compatibility with Cold Mounting Resins: Fully compatible with all types of two-component epoxy cold mounting resin and acrylic cold mounting resin, no chemical corrosion or reaction with resin materials, no impact on resin curing speed, hardness and molding effect.
-
Reusable & Cost-Effective: High-quality raw materials ensure excellent durability, not easy to break, deform or wear after repeated use and cleaning, greatly reducing the frequency of mold replacement and lowering laboratory consumable costs compared with disposable molds.
-
Simple Structure & Easy Operation: Designed with split cylindrical (base + side wall) or integrated cylindrical structure, no complicated assembly steps required. Easy to place samples, pour resin and clean residual stains after use, suitable for both professional operators and beginners.
-
Corrosion & Stain Resistance: The mold surface has dense texture, resistant to corrosion of cold mounting resin and curing agent, not easy to absorb stains and residues, easy to clean and keep tidy, maintaining stable performance after long-term use.
