Plastic molds are tools in the plastics processing industry that are used in conjunction with plastic molding machines to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, the structure of plastic molding machines and plastic products is not simple, so the types and structures of plastic molds are also varied.
classification
The general classification of molds can be divided into plastic molds and non-plastic molds:
Non-plastic mold
(1) Non-plastic molds include: casting molds, forging molds, stamping molds, and die casting molds.
A. Casting mold - faucet, pig iron platform
B. Forging Die - Auto Body
C. Stamping Die - Computer Panel
D. Die Casting Die - Superalloy, Block
Plastic mold
(2) Plastic molds are divided into:
A. injection molding mold - TV housing, keyboard buttons (the most common application)
B. Blow Mold - Beverage Bottle
C. Compression Mold - Bakelite Switch, Scientific Porcelain Dishes
D. Transfer Molding - Integrated Circuit Products
E. Extrusion Molding - glue pipe, plastic bag
F. Thermoforming Mold - Transparent Molded Package
G. Rotary Molding - Soft Rubber Doll Toy
Basic knowledge of plastic mold products
A combined plastic mold for compression molding, extrusion molding, injection molding, blow molding, and low foam molding, which mainly comprises a variable cavity composed of a female die combination substrate, a die assembly and a die combination card board The female die comprises a punch with a variable core, which is composed of a male die combination substrate, a male die assembly, a male die combination card board, a cavity cutting assembly and a side cut assembly board. Coordinated changes in the convex, concave, and auxiliary molding systems of the die. Can process different shapes, different sizes of series of plastic parts.
The various tools and products used in our daily production and life are as large as the base of the machine tool, the shell of the machine body, and the size of a single head screw, button, and shell of various household appliances, all of which are closely related to the mold. The shape of the mold determines the shape of these products. The quality and accuracy of the mold determines the quality of these products. Because of the different materials, appearances, specifications, and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds.
Colorful resin road surface is composed of special polyurethane adhesive source agent and high temperature color bai ceramic aggregate.
Color non-slip pavement performance: zhi
1. It can significantly increase the dryness of the road and the anti-skid performance in rainy days, and shorten the braking distance by more than 40%
2. The color is rich and optional, the color is gorgeous and lasting, the whole body is one color, never fade, no color difference
3. Light weight, will not increase the bearing burden of bridges and pavement foundations
4. The material has good waterproof performance, which makes the pavement surface closed, has anti-rutting performance, reduces or prevents pavement cracking, and improves service life
5. Absorb car waves, reduce noise by 6-7 decibels, and reduce noise by about 30%
6. Low temperature brittleness, which is beneficial to use in severe cold areas
7. Excellent thermal aging performance, good high temperature stability, effectively prolonging the service life of the road
