Functionality of PP Compression Fitting Molds
PP compression fitting molds are designed to shape molten polypropylene into precise forms that are needed for compression fittings. These molds consist of multiple cavities that define the shape and size of the fittings. The molten PP material is injected into the mold cavities, where it solidifies and takes the desired form. The molds ensure accurate dimensions, tight tolerances, and smooth finish of the compression fittings.

Importance of Material Selection for Molds
Choosing the right material for PP compression fitting molds is crucial to achieve optimal results. The molds need to withstand high temperatures and pressure during the injection molding process. Typically, materials like high-strength steel or aluminum alloys are used for mold construction due to their excellent thermal conductivity, durability, and resistance against wear and corrosion. The material selection directly affects the mold’s lifespan and the quality of the produced fittings.
