Research on Machining Technology of PMMA
PMMA plexiglass material is characterized by low melting point, easy shrinkage, brittleness, and intolerant of organic solvents. PMMA material is used in the valve body, which has high transparency, easy observation, and high cost performance. It is a very commonly used material.
The machinability of the PMMA valve is still good. As long as the appropriate processing skills are used, the problem of cracking caused by screwing can be effectively avoided. PMMA has high dimensional stability after machining, and with the unique PMMA polishing technology of Chengtu Plastics, high dimensional accuracy can be achieved.
PMMA polishing, traditional use of flame polishing, high permeability, no knife marks on the surface, beautiful and clean appearance, but there are shortcomings, the size shrinkage is larger, and the place with holes, the shrinkage is larger. PMMA mechanical polishing process can effectively solve the problem of size shrinkage. And low cost, easy to mass production.
