In order to better use the mold, we need to choose according to specific requirements when purchasing mold accessories. The common requirements for mold accessories mainly include the following points:

1: Simple installation and how to maintain the parts: Check whether simple and clear installation instructions are delivered. Where applicable, the products packaged together should also be marked with which maintenance steps, such as cleaning, lubrication, disassembly and replacement steps.

2: Product price, whether it includes tax and freight: These mold parts should have a market-competitive value-added space, and must be real materials and not fake.

3: Part interchangeability: After a period of time, when the supplier’s part design changes, you can replace the previous version in time. Global replacement: It is necessary to ensure that you can find the same mold parts replacement anywhere in the global market.

4: Stability and traceability of product quality: Your suppliers must have relevant quality stability records and trace any products they produce. Compatibility of mold accessories: Ensure that the mold accessories you buy are compatible with any other accessories in the mold to facilitate operation on the mold, so as to avoid product approval or failure to try out the mold.

5: Product range and material sources and the effectiveness of non-standard accessories: Check additional mold parts to ensure that they can be easily found and replaced when different materials or sizes are required.

6: Product certification: For example, HASCO and European product processes have all passed ISO9001:2000 certification, which ensures the quality stability, traceability and effective documentation of mold parts throughout the order and assembly process.

In the future, the development speed of plastic mold accessories will be higher than other molds

The regional characteristics of China’s mold industry are obvious, mainly as follows: the development of the southeast coastal area is faster than that of the central and western regions, and the development of the south is faster than the north. The most concentrated areas of mold production are in the Pearl River Delta and the Yangtze River Delta, accounting for more than 2/3 of the national mold output value.

It is understood that in recent years, the development of China’s plastic mold accessories has been quite rapid. At present, the proportion of plastic mold accessories in the entire mold industry is about 30%. With the rapid development of China’s automobiles, home appliances, electronic communications, and various building materials, it is expected that in the future mold market, the proportion of plastic mold accessories to the total mold will gradually increase, and the development speed will be faster than other molds. Take the automobile industry as an example. With the rapid growth of automobile production and sales, the potential market for automobile molds is huge.

In the production of automobiles, various functional parts must be formed by molds. It takes more than 200 interior trim molds to manufacture an ordinary car, while the large and medium-sized ones needed to manufacture bumpers, instrument panels, fuel tanks, steering wheels, etc. From the perspective of the production capacity of the mold industry, the current satisfaction rate of plastic mold accessories is only about 50%. In the construction field, it is also a general trend that plastic building materials will replace traditional materials in large quantities. It is estimated that in 2010, the penetration rate of plastic doors and windows and plastic pipes will reach 30%-50%, and the market share of plastic drainage pipes will exceed 50%, which will greatly increase the demand for molds. the amount. It should be said that the application potential of plastic mold accessories cannot be underestimated. Experts predict that large-scale, precise, and well-designed injection molds will be generally welcomed by the market.

Plastic mold accessories have formed a huge industrial chain. In recent years, my country’s plastic mold accessories have formed a huge industrial chain driven by high technology and the application demand of pillar industries, from the upstream raw and auxiliary materials industry and processing and testing equipment to In the downstream industries such as machinery, automobiles, motorcycles, home appliances, electronic communications, building materials and other major application industries, the development of plastic mold accessories is full of vitality. At present, the application of plastic products is becoming more and more extensive, providing a broad market for plastic mold accessories, and at the same time putting forward higher requirements for molds. Large-scale, high-precision, multi-functional composite molds will be favored. At the same time, industries such as construction, home appliances, and automobiles have a great demand for plastics.

The hardness of mold parts is the main factor affecting wear resistance

Core Abstract: The hardness of mold parts is the main factor affecting wear resistance. In general, the higher the hardness of the mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.

1.Strength

The working conditions of the molds are mostly very bad, and some of them are often subjected to large impact loads, which leads to brittle fracture. In order to prevent sudden brittle fracture of mold parts during work, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organization state of the material.

2.Wear resistance

When the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing violent friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.

3.Fatigue fracture performance

During the working process of the mold parts, under the long-term action of cyclic stress, fatigue fractures are often caused. Its forms include low-energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
