Overcoming the problem of thin-walled deep cavities, Kaiji's thin-walled container moulds for lunch boxes are exported in bulk to Europe and America

For high difficulty thin-walled products such as fast food boxes, disposable water bottles, and thin-walled storage containers, the company's technical team optimized the exhaust system and needle valve hot runner structure to solve the problems of product shrinkage, warping, and uneven wall thickness.
At present, multiple thin-walled lunch box moulds have been steadily mass-produced, with a wall thickness of up to 0.35mm and stable high-speed injection molding, meeting the production requirements of European and American food grade plastic products. Recently, many sets of thin-walled packaging moulds have been successfully sent to customers in Poland and Türkiye, becoming a new growth point of the company's foreign trade.
