Hengyang Huayi developed a multi-layer co-extruded blow molding machine

The multi-layer co-extrusion and multi-cavity hollow machine manufactured by Huayi Rubber Machinery Co., Ltd. of Hengyang City, Hunan Province fills the domestic gap.
China is a big agricultural country. Pesticides and agricultural production are inextricably linked. Traditional and aqua pesticides are filled with glass bottles. Glass bottles are easily damaged during packaging and transportation. Discarded pesticide bottles cause environmental pollution. Plastic bottles contain lighter pesticides, and used bottles can be recycled and cost-effective. At the end of the 1980s, some manufacturers in China considered changing to plastic bottles for pesticides. However, a single-layer plastic bottle cannot simultaneously have properties such as water blocking, chemical composition leakage resistance, high impact strength, and the like, and the corrosiveness of the pesticide is strong, and leakage is easily caused, causing unnecessary loss and unsafe factors. However, the market for plastic bottles has a bright future, so manufacturers have turned their attention to the research and development of multi-layer plastic bottles.
Huayi Company followed the change of market demand and developed and produced a three-layer co-extruded, one-cavity four-cavity, full-computer automatic blow molding machine for a customer in Hangzhou, Zhejiang. The company's three-layer co-extruded blow-molding machine, a molded out of four products, duplex positions, a cycle out of eight products, greatly increasing production and saving energy. Zhejiang customers are very interested in such high quality, low-priced equipment, ordering four sets at a time. The advent of this multi-layer co-extrusion and multi-cavity blow molding machine has filled the gap in the domestic market.
