ABS material is a kind of simple and common plastic alloy. With the excellent physical and chemical properties and strong wear-resistance, it is mainly applied in mechanical parts and wear-resistant parts. Recently, a customer went to Taili Plastic Machinery with a question that how he can improve the lightness of ABS with the mold well-polished?
We first inquired about the production temperature, because the decomposition temperature of ABS materials is generally 270 degrees. For plastic parts with high requirements on surface accuracy and wear resistance, the temperature of the reclaiming cylinder is about 250 degrees and the mold temperature is about 60 degrees. If the requirement of surface smoothness is high, the raw materials need to be pre-dried for about 3 hours. Because if the moisture content in the raw materials is too high, the moisture will volatilize into vapor state in the production process, and condense in the mold cavity to form water mist, resulting in the decline of the surface finish of the mold.
After eliminating the reasons of materials, more than 80% of the surface finish of ABS plastics is caused by over low injection speed and improper packing operation. The fluidity of ABS material is not very good. If the injection speed is too small, the material on the surface of the product will not be compact, resulting in water inclusion and atomization surface problems. By properly increasing the injection speed, reducing the injection pressure and increasing the holding time and pressure, the surface finish of the product will be greatly increased.
What the customer chooses is some other brand of injection molding machines whose size is about 280 tons. Due to the limitation of machine performance, the injection speed can’t be increased. We suggest him to use a machine with a little larger tonnage, such as about 360 tons, to optimize the surface accuracy of the product. The only defect is that the power consumption will increase slightly.
When he came into Taili plastic machinery’s factory, we let him try out on the 280 ton machine of TLE fast machine series in our factory. Because my injection molding machine has been specially optimized for his product and the injection speed is greatly improved, the 280 ton injection molding machine of TLE fast machine series can also be used for his production. If other brands of injection molding machines are selected, I suggest them to use machines of more than 360 tons.
Taili Plastic Machinery always keeps in mind that what a good injection molding machine factory should do is to help improving the capacity and boosting the profits, rather than offer the similar products the customers need. This is also what Taili Plastic Machinery keeps doing.
