Injection Molds and Plastic Injection Molding Products

The injection molding process in china， the process produces large numbers of parts with high quality， great accuracy, and quick cycle time. The production of plastic injection molds from both thermoplastic and thermosetting plastic materials. The plastic material, in the form of particles, is melted until it is soft enough to be injected under pressure, either through a reciprocating screw or a ram ejector, into the mold cavity. In China, when a part is designed by the customer, then manufacturing molds by an injection mold company, it needs a mold maker (or toolmaker) team to build. The result is that the shape is exactly copied. Once the plastic injection molding has cooled sufficiently to harden the mold opens releasing the part. The whole injection moulding process then repeats.

Injection mold making in China. We usually manufactured using steel or aluminum. And precision-machined to form the features of the desired parts. Injection molding is widely used for manufacturing a variety of parts, including household appliances, consumer electronics, power tools, and automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well.




Injection Mold situation in China

China's rapid economic development of the tooling industry put forward higher requirements and has provided great impetus for its development. In the past 10 years, China's mold industry has been rapidly developing at about a 15 % per year growth rate. In recent years, the mold industry to accelerate the pace of structural adjustment, mainly for large, sophisticated, complex, long-life mold standard parts, standard mold growth rate higher than the overall growth rate of the industry; a larger proportion of plastic and Die-casting mold; Despite the development of China's mold industry, there is an imbalance in the geographical distribution of the mold industry， The most concentrated area of mold production is pearl river delta and Yangtze river delta. Which accounts for over two-thirds of the country's mold output value.

China's market leader Dies, Shanghai is China's leading injection molds market today and is China's largest export mold city. 40% of the value of the multinational mold from Shanghai, and the performance rate of NC mold processing equipment and equipment, mold processing technology, the degree of specialization in production levels and standards ahead of other provinces. With further industrial structure optimization, developing IT, automotive, high-tech, and other industries are Shanghai mold manufacturing to higher requirements. Next few years, Shanghai mold manufacturing will become increasingly sophisticated, and complex. Private companies such as CNMOULDING's growth rate of 100 %, become important members of the china injection mold industry.

Applications of China Injection Molds

Plastic Injection molding in China is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which varies greatly in their size, complexity, and application. The plastic injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section a popular material for Injection Molds

Equipment

China Plastic Injection Molding Machine-Injection Molding Process

Injection molding machines, also known as presses, consist of a material hopper. An injection ram or screw-type plunger, and a heating unit. The molds are clamped to the platen of the molding machine. Where plastic is injected through the sprue orifice to create injection molds.

Here we especially introduce a high-speed injection molding machine in China.

1. High-speed injection molding machine Clamping Unit

The new generation toggle mold locking device. And computer emulation optimized toggle parameter makes motions of the moving plate fast and steady.

2. High-speed injection molding machine Hydraulic Unit

High efficiency, energy-saving, and high precise proportional pressure. And the flow variable displacement pump system makes the hydraulic system output match. The required power for the entire machine operation without high-pressure throttle and overflow energy loss.

3. High-speed injection molding machine Injection Unit
The short and forceful double-cylinder injection system is used to ensure steady injection motions. The strain-free fixed mold plate and screw assembly with optimized design help to reach better plasticating capacity and effect.

4. High-speed injection molding machine Control Unit
The high-performance special control for injection molding machines. Switch of Chinese and English, clear and visual, and easy operation.

Mold making in China

Mold is the common term used to describe the tooling used to produce injection molded plastic parts.
It is mainly the production of thermoplastic products the most common kind of mold. Plastic injection mold processing equipment for the plastics injection molding machine. Plastic melt is first heated in the heated barrel of the end of the injection machine. And then injection molding machine into the mold cavity under the impetus of a screw or a plunger. The injection machine nozzle and mold casting system. Plastic cooling hardening molding, and mold release to get the products. Its structure is usually molded parts, casting systems, and parts-oriented components. The introduction of institutions, thermostat systems, exhaust systems, and support components.

Manufacturing materials commonly used plastic mold steel modules, commonly used material is mainly carbon structural steel, carbon tool steel, alloy tool steel, and high-speed steel. The injection molding process usually applies only to the varieties of products. Production of the thermoplastic injection molding process to produce plastic products is very extensive. From the daily necessities of life to all kinds of complex mechanical, electrical, and transport parts are injection molding. It is the most widely used in the production of plastics processing methods.
