Factors affecting the precision of parts produced by injection mold: 1) Molding materials: plastic shrinkage, fluidity, moisture, volatile content, raw material allocation process, production batch, etc. can affect the precision of plastic parts produced by injection mold. 2) Process conditions: molding temperature, pressure, time, shrinkage.; 3) Part shape: shape, wall thickness, molding shrinkage, demoulding slope, etc; 4) Injection mold: manufacturing precision, wear degree, shape and structure, shrinkage direction; 5) Aging change after forming: post shrinkage,

Classification of automobile die sizes 1. Small mold ≤ 1000mm Other small accessories such as A pillar and B pillar in the interior of the car, as well as threshold strip, door panel guard board, and rear-view mirror in the exterior decoration belong to the scope of small molds. 2. 1000mm ≤ medium mold ≤ 1500mm The C-pillar, center console, front and rear door panels, trunk guard, exterior middle lights, grille, etc. in the interior

Although the structure of the mold may vary greatly due to different types and properties of plastics, shapes and structures of plastic products, and types of injection machines, the basic structure is the same. The mold is mainly composed of gating system, temperature regulating system, molding parts and structural parts. Among them, the gating system and molding parts are the parts that directly contact with the plastic and change with the plastic and products. They

Difference between plastic mould and two-color mould   1. Two-color mold: a mold in which two kinds of plastic materials are injected on the same injection machine and molded twice, but the product is only molded once. Generally, this molding process is also called double injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. Two-color mold can make two resins and colors with different characteristics
