The Injection Blow Molding Machine, often referred to as a preform injection molding machine, is the critical first step in the PET bottle manufacturing chain. It produces the precise, test-tube-like preforms that are later reheated and blown into their final bottle shape. The quality of the preform directly determines the clarity, strength, and consistency of the finished PET bottle, making this machine a vital investment for integrated bottle producers or those supplying preforms to the market.
Our machines excel in delivering high-precision, high-output preform production. They utilize advanced injection molding technology to ensure each preform has exact weight distribution, superior material homogeneity (essential for preventing defects like haziness or weak spots), and perfect neck finish geometry for reliable sealing. A significant advantage is the integration of a blowing station within the same cycle in a true injection-blow process, although our focus is primarily on the high-speed, multi-cavity injection molding of PET preforms for later use on separate stretch blow molders.
We prioritize energy efficiency and operational stability. Modern servo-driven systems reduce power consumption significantly compared to traditional hydraulic machines. Key parameters defining these machines include the number of cavities (directly influencing output), the shot weight (determining preform size and weight), and the clamping force. For businesses aiming to control their entire supply chain or produce preforms at a competitive cost, our injection blow molding machines offer the technological foundation for consistent, top-tier raw material production.
