pet preform mould Specification:

Features:

Mould plates are P20 Steel with pre-hardening process. Core, cavity and neck screw are made of S136 high strength anti-corrosive stainless steel, which is better than 48HRC.

Mould plate is completed by one-time processing to ensure the concentricity of molding hold and guide bush, guaranteeing the compact structure of the mould.

Opening/closing pulling plate (material S136) adopts bearing slide type to drop the perform with reliable structure. And it is a highly integrated process of slider, pushing plate and ejection. All sliding parts surface inlaid self-lubricating copper alloys to ensure low friction coefficient and strong wear-resistant.

The main components are consistent with various well-know foreign brands, high positioning accuracy and convenient disassembly.

Reasonable and quick spiral cycle waterway can get rapid cooling effect to shorten cycle time.

Adopting double cone positioning principle guarantees high manufacturing precision to ensure the product does appear flash, different sizes, irregular and other defects.

Neck screw is processed by famous brand equipment. The dimension is accurate and consistent

Moulding part hardening makes the friction surface stable, identical and durable in use.
