Injection molding is an important industrial method. It is somewhat similar to die casting, but the difference lies in the raw materials used. In die casting, the metals we use require extremely high temperatures to melt, but injection molding is mainly performed on glass, elastomers, and the most common thermoplastic and thermosetting polymers, but this technology has been widely used to make thermoplastic materials. The process is completed by heating the raw material and applying pressure at a specific temperature to inject it into the mold cavity without any change in its chemical composition.

In the injection production, plastic injection molding parts cooling time of the entire injection production cycle of about 80%. Poor cooling often results in warpage of the product or surface defects, affecting the dimensional stability of the product. Tsim nyog, packing and cooling time, can improve product quality and productivity. Part of the cooling time, usually refers to …

1: The die must be grinded after a long time use, after grinding the edge surface must be demagnetized, can not have magnetic, otherwise easy to occur blocking material. In order to find out which parts and components have been damaged and the degree of wear, the enterprises should make detailed records and statistics of their use, care (lubrication, cleaning, …

1. Moulds refer to precision forming tools used for batch forming, stamping and other products. The accuracy of the mold includes the accuracy of the parts obtained in processing and the production time guarantee It can prove the quality awareness of product accuracy, but the mold accuracy usually refers to the accuracy of mold working parts. ①. The concept of …

There are many friends who are engaged in the injection molding industry. Because they are only engaged in one of the varieties, they may not know much about other molds, but we can learn more about the upstream and downstream of the mold industry by understanding the mold industry as a whole, so I All types of molds are classified. …

Why use baked plastic raw materials? ABS, PC, PA6 types of plastic raw materials need to be baked, but PP, TPO, POM types do not need to be baked? In the injection molding process, the moisture content of the material must be in a relatively low range to ensure the normal injection molding and the normal physical properties of the …

Electrical parts 1. Wire connector inspection Unfastened wires in the connector will cause high temperature or spark damage at the connector position. A poor connector will also affect the signal transmission; the connector on the contactor will be easier to loose due to the vibration of the electromagnetic action, so it is necessary to check the wire connector regularly Position …

Causes and solutions of injection machine failures 1. The oil temperature is too high The abnormal increase in oil temperature may be caused by abnormal cooling system or high heat generated by oil pressure components during operation. 1. The cooling system is abnormal 1) The supply of the cooling system is insufficient, such as the water switch is not fully …

According to the “Basic Situation of National Mould Professional Factory” compiled by the Operation Management Committee of my country Mould Industry Association, my country’s mould is growing at an average rate of over 15%, which is more than double the average value-added of domestic GDP. Ntawm lawv cov, casting molds account for about 5% of the total output value of various …

The strong development of Zhejiang injection machine industry As a pioneer in China’s reform and opening up, Zhejiang muab cov hlau lead hauv txoj kev loj hlob industrial. Tom qab xyoo lawm ntawm txoj kev loj hlob ceev, Tag nrho machinery kev lag luam muaj tau ceev zoo tuaj, and many injection molding machine companies have slowly mastered the previous processing and manufacturing. Ntxiv rau cov tub ntxhais ntau lawm tshuab, more large-scale enterprises …

1. Control the production of defective products, (control defective products) 2. Improve mold efficiency, mold efficiency directly affects the amount of material used. 3. Control inventory to avoid inventory caused by excessive production. 4. Cultivate the concept of cost saving for technicians, and avoid too much waste when adjusting the injection molding machine. 5. Confirm the change of the product …
