PEI Injection Molded Sight Housing

This is a PEI injection molded sight housing. The mold is made of high quality mold insert steel H13 and the hardness of the steel reaches HRC48-52, the life of the mold can exceed 500,000 shots or more when the mold is well maintained. PEI is a high-performance engineering thermoplastic known for its exceptional mechanical, thermal, and chemical properties. PEI molds are molds made from or coated with Polyetherimide material. PEI can withstand elevated temperatures without significant deformation, making it suitable for molding high-temperature thermoplastics. The presence of glass fibers helps reduce the coefficient of thermal expansion, leading to better dimensional stability and reduced risk of warping during molding and high-temperature applications. The appearance of the product is perfect, there is no flash, and the size meets the requirements. Our company is a professional manufacturer of PEI  Mould, PPSU Mould, PSU Mould, PEEK Mould.
