Which process is more expensive, blow molding or injection molding? We are looking for a professional one-step injection blowing PC blow molding lampshade manufacturer.

Blow molding is more expensive than injection molding! Guangzhou Runxi Plastic Industry Co., Ltd. is a professional manufacturer adopting one-time injection blow molding technology. The company's main products are LED bulb lamp lampshade, ultra-semicircle lampshade, large-angle luminous PC lampshade, spherical PC lampshade, bulb lamp PC lampshade, blow-molded PC lampshade, LED ultra-semicircle PC lampshade, LED bulb lamp lampshade, PC bulb lamp lampshade and so on. It can be analyzed that blow molding is more expensive than injection molding from three aspects: 1. Process. Blow molding, that is, one-step injection blowing process, injection molding and blow molding are completed in one step, realizing full-automatic production and reducing manual operation. On the one hand, it can increase output, on the other hand, it can save raw materials and reduce costs. Injection molding is to inject first, and then put it into the mold for manual reproduction. Manual operation will definitely increase the rejection rate and cause waste; 2. Mold cost. One-step injection-blow process has five sets of molds, namely three upper molds and two lower molds, and one set of molds is also a combination of injection molding and blow molding, so the mold cost is high. The cost of injection mold is relatively low! 3. Production capacity. One-step injection and blowing process can realize fully automatic production, and one machine can produce 7-8K a day, which is far ahead of the injection molding process. Guangzhou Runxi Plastic Industry Co., Ltd. provides professional one-step injection and blowing technology: 1. Injection-blowing molding at one time, no burr waste, and improved strength.
