Analysis of craze for injection moulding products of polyetherimide using SEM
Owing to high requirement aesthetic perception for the open-faced cellphone lens, injection moulding was more preferably adopted instead of traditional cutting process.
The following processes employ pressure to shape the plastic: injection moulding（注塑）, extrusion（擠出）, blow moulding（吹塑）, rolling（壓延）, drawing（拉延）, bending（彎延）, stamping（衝壓）, and all methods of fabrication by machining.
To increase productivity, maximize on the number of cavities by using the clearance between tiebars, the platen dimensions and the injection weight of the injection moulding machine to the most.
Since the establishment of PO YUEN in1963, we have accumulated over35 years of professional experience in manufacturing injection moulding machines.
The retroreflector formed by arrays of cube corners is produced with the optical plastics by means of injection moulding.
