Sliding injection molding is primarily used for the manufacture of hollow products. It involves splitting the hollow product into two semi-finished products. The two semi-finished products and the injection mold are then slid together for a second close-fitting process. Plastic melt is then injected into the joint between the two parts to create a complete hollow product. This type of custom hollow product mold offers the following two advantages. HUIWEN will discuss these advantages and mold classifications below.
1. Advantages of Plastic Molds for Complex Hollow Products:
1. The semi-finished product does not need to be removed from the mold, thus avoiding the problem of reduced shape accuracy caused by cooling the semi-finished product outside the mold. This also avoids the problem of reduced weld strength caused by localized stress in secondary welding.
2. It offers advantages such as excellent surface finish, high dimensional accuracy, uniform wall thickness, and greater design freedom.
2. Due to the wide variety of plastics and processing methods, the types and structures of molds are also diverse. They can generally be divided into: plastic molds and non-plastic molds.
(1) Non-plastic molds include: casting molds, forging molds, stamping molds, die-casting molds, etc.
A. Casting mold - faucet, cast iron platform
B. Forging mold - car body
C. Stamping mold - computer panel
D. Die-casting mold - super alloy, cylinder block
(2) Plastic mold
According to the production process and the product, it can be divided into:
A. Molding mold - TV shell, keyboard button (widely used)
B. Blowing mold - beverage bottle
C. Compression molding mold - Bakelite switch, scientific porcelain bowls and plates
D. Transfer molding mold - integrated circuit products
E. Extrusion molding mold - glue tube, plastic bag
F. Thermoforming mold - transparent molding packaging shell
G. Rotational molding mold - soft plastic doll toys
