Professional molding of thick walled plastics such as PMMA, PC, ABS, etc., with no injection marks, jet marks, or weld marks on the surface of the product, stable size, no bubbles or shrinkage inside, using a dedicated sequential temperature control injection molding method, suitable for molding transparent products with a thickness of 3-70mm, and can also be used to mold ordinary plastic products with high surface requirements.
Principles and characteristics：
The plasticizing system of the optical grade plastic injection molding machine adopts specialized screws and highly wear-resistant material barrels. Different wear-resistant materials can be selected for PC or PMMA raw materials to apply to professional injection molding. Meanwhile, BESTON also provides customers with standard "precise screw positioning" functionality. Through precise screw positioning function, it can be combined with injection compression process to make the injection molding part highly repeatable. The dual displacement structure ensures the safe and reliable sealing of the nozzle during high-pressure injection, while the linear injection guide provides reliable hardware assurance for high-quality injection and plasticization processes
Airprint defects are a difficult problem to solve in some high demand products:
For industries with high cleanliness requirements, powder coating technology is used on the outside of the machine, which has good scratch resistance and corrosion resistance to cleaning agents. The important moving parts adopt drip free lubrication technology. Compared with ordinary machines, BESTON's advantages are more prominent and play a very important role. In the conditions of a dust-free workshop, the cleaning of the working area floor is very important. In order to facilitate the cleaning of the floor, BESTON can raise the machine base plane by 120mm according to customer requirements.

Technical core/independent patented technology:
One of the core technologies
The grouping sequential temperature control technology is adopted, and even high-quality multi cavity products can be obtained in the case of using point gate cold runner. The injection molding machine can choose 10 or more sequential temperature control functions to flexibly adapt to different product and mold structure requirements. The specifications of this injection molding machine are from 90 tons to 350 tons.
The second core of technology
Superior performance indicators, injection pressure can reach up to 310Mpa, using fully closed-loop control technology with a deviation of less than 0.1Mpa. According to different requirements, the injection speed can be selected from a range of extremely low speed 0.1mm/s to high speed 300mm/s.
The third core of technology
We can provide negative pressure vacuum plasticization technology to customers in need at any time, greatly reducing the drying requirements of raw materials. Moreover, the molding process has no patterns or bubbles, and because it reduces the contact between high-temperature materials and air, the chance of product high-temperature decomposition and discoloration is greatly reduced. It is particularly suitable for injection molding production of high-quality and heat sensitive raw materials.
Core Technology 4
According to the injection molding of some products with excessive weight, double stage injection molded parts can be selected to achieve large capacity and ultra precision injection molding, suitable for molding thick walled injection molded parts with low clamping force requirements but high product weight and injection pressure.
