New PET Injection Mould Technology Makes It Possible to Produce Smaller Quantities of Preforms
Sep 01,2022
A new injection moulding technology has made it possible to produce smaller quantities of PET preforms. The new Arburg machine from Germany features a valve-gated hot runner that allows up to four cavities to be produced in a single cycle. This feature can make the process more economical and efficient. The machine also allows a smaller sample quantity to be produced, which is a plus for companies that need small quantities of sample materials for a variety of applications.
PET preforms are formed by an electrochemical reaction between two metals. The process results in a sleek coating that is more resistant to wear and tear than the standard metal finish. The finished PET preform mould is then dipped in a chemical solution to add a protective coating.
The injection of PET preforms is a challenging process that demands an injection moulding system with a high melting point and short time after melting. A two-circuit hydraulic design makes the process fast and efficient. It is important to note that the actual weight of the product cannot be less than two-thirds of the machine's injection volume. In addition to the high melting point, PET injection systems need a high clamping force.
