The temperature of the PET preform mold is precisely controlled to prevent warping. Deformation is an important factor, therefore the use of a hot runner mold is recommended. The tool temperature should be high, otherwise there will be poor surface gloss and difficulties in demolding. What are the m

PET preform mould requires high precision, the difficulty lies in the thin wall of the test tube, the concentricity of the mold is difficult, the output of the test tube is relatively large, 8 cavities, 16 cavities, 32 cavities are relatively common, so the steel material of the mold should be selec

This article outlines the key advantages, applications, and production role of high-performance PET preform moulds. Key benefits include cost-saving interchangeable parts, a double-cone clamping design that prevents defects like flash, and the use of durable S136 steel capable of over 5 million cycles. These molds are essential for mass-producing containers like mineral water and carbonated drink bottles, supporting configurations of up to 128 cavities for maximum efficiency. In production, the mold ensures quality stability through a hot runner system and precise water-cooling, with all designs backed by rigorous testing and readily available spare parts for minimal downtime.
