What are the differences between plastic trial molds and cast iron trial molds

What are the differences in materials used for plastic and cast iron test molds

1. Lightweight, 8-10 times lighter than cast iron molds of the same specifications, reducing manual labor intensity.

2. It eliminates the process of installing and removing the cast iron mold, as it is a whole and can be demolded with an air pump (or pump), allowing one person to quickly demold and improve work efficiency.

3. Improved the accuracy of the test piece, as the plastic test mold is successfully injected with high-precision engineering plastic molds in one go, reducing the human error caused by the installation of cast iron molds.

4. Engineering plastic test molds have high strength, high temperature resistance, and low temperature resistance. They do not deform within the range of -30~+100 and can be used normally.

5. Long term use is cost-effective, with low unit price and reduced labor, while eliminating the hassle of replacing bolts and nuts in cast iron molds.
