What is a mold?
Molds are various molds and tools used in industrial production to manufacture required products, which are realized through injection molding, blow molding, extrusion, die-casting, forging, smelting, stamping and other methods.
In short, it is a tool that turns a blank into a workpiece of a specific shape and size under the action of external force. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object through changes in the physical state of the molded material. Molds are known as the "Mother of Industry" because they play a vital role in production and are widely used in various forming processes, such as blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, Pressure casting, as well as compression molding or injection molding of engineering plastics, rubber, ceramics and other products.
Mold composition
The mold usually consists of two parts: the movable mold and the fixed mold (or punch and concave mold), which can be separated or combined. Separate to take out the workpiece, and when closed, the blank is injected into the mold cavity for forming. Molds are precision tools with complex shapes that need to withstand the bulging force of the blank. Therefore, they have high requirements for structural strength, stiffness, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of machinery manufacturing. Molds are used in a wide range of applications. In our daily lives, many items such as bathtubs, wash basins, rice cookers, computers, mobile phones, and even many parts of cars are produced by molds.
In addition to the mold itself, the mold also requires a mold base, a mold frame, a mold core, and an ejection device for the product. These components are generally made into universal types. If our mold companies need to become bigger and better, they must determine product positioning and market positioning based on market demand, technology, capital, equipment and other conditions, and concentrate on gradually forming their own technical and product advantages. Therefore, our mold companies must actively strive to learn from the experience of these advanced foreign companies for better development in the future.
Main uses of molds
A mold is an industrial tool that changes the physical state of the molded material to produce parts with specific shapes and sizes. There are many types of molds, including injection molds, die-casting molds, stamping dies, precision forging dies, etc. Each mold is suitable for different materials and production processes. Molds play a vital role in modern industry, not only improving production efficiency and product quality, but also reducing product manufacturing costs.
Production of plastic products: such as casings and components of automobiles, home appliances, electronic products, and daily necessities such as kitchenware, furniture, shoes, toys, etc.;
Production of metal products: including automotive engine parts, transmission parts, and other machinery and equipment components;
Production of medical devices: especially precision molds, used to produce medical products that require high precision and quality.
In products such as electronics, automobiles, motors, instruments, electrical appliances, meters, home appliances, and communications, 60% to 80% of parts must be formed by molds. The high precision, high complexity, high consistency, high productivity and low consumption demonstrated by using molds to produce parts are unmatched by other processing and manufacturing methods.
