Abstract

The invention provides a control panel for injection molding. The control panel comprises the following raw materials in parts by weight: 60-70 parts of PC (polycarbonate) resin, 15-25 parts of a panel filler, 5-11 parts of a metallic oxide and 1-3 parts of a disperse lubricating agent. The control panel has the benefits that the control panel is good in abrasion resistance, flame retardance and aging resistance; in addition, the control panel is relatively high in hardness and relatively good in antibacterial activity, so that the service life of a finished product is prolonged; the used rawmaterials are easily obtained and environmentally-friendly, and the control panel is simple in production steps and low in production cost.

Description

technical field [0001] The invention belongs to the field of plastic injection molding, and in particular relates to an injection molding control panel. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. [0003] The material of the existing injection molding control panels is usually polyvinyl chloride, which has relatively weak insulation, low hardness, and low anti-aging performance; the injection molding production process is not e...
