PBT with glass fiber is a commonly used engineering plastic for electronic connectors and new energy precision structural components. Featuring high hardness and unique brittleness after glass fiber filling, it poses great difficulties for traditional manual deflashing: the mold flash is hard to trim, manual operations are likely to cause chipping and surface scratches on parts, with low processing efficiency and inconsistent finished quality. This has long troubled many injection molding manufacturers.
To address the deflashing pain points of PBT+GF materials, the STMC Jishe series cryogenic deflashing machine provides a proven automated solution. Based on the liquid nitrogen low-temperature embrittlement principle, it precisely controls the processing temperature. Only the thin flash becomes brittle, while the main body of the workpiece remains free from damage caused by low temperature and pellet impact. The original dimensional accuracy and mechanical properties of glass fiber parts are fully preserved, and fine parting lines and burrs on holes can be removed in one pass.
Equipped with self-developed temperature control and blasting systems, the Jishe series cryogenic deflashing machine supports adjustable parameters and is suitable for mass production of PBT+GF parts of various specifications. A large number of workpieces can be processed in a single batch, largely replacing manual trimming, cutting labor costs, reducing rework rates and steadily improving yield. Free sample testing is available to support injection molders with customized process solutions.
With years of expertise in low-temperature deflashing technology, STMC specializes in the R&D and manufacturing of cryogenic deflashing machines, featuring mature processes and a comprehensive after-sales service system. For cryogenic deflashing of PBT+GF parts, the STMC Jishe series cryogenic deflashing machine is your ideal choice. Choose STMC, choose peace of mind.
