china vertical double slide Injection Molding Machine.

Vertical Single Slide Injection Molding Machine For the old products, the process parameters shall be input before normal operation, and the batch production shall be started after the quality inspection. If it is a new product, the operation steps are as follows:

① Set the barrel temperature to the normal molding temperature. Set melt and injection stroke according to product weight.
② Determine the injection pressure and speed according to the injection process. Medium pressure (50~80MPa) and rotating speed (30~60mm/s) are usually used.
③ Determine the pressure holding time according to the gate type and size. Precise positioning of the door, 6-8 seconds; Side door and direct door, 8-10 seconds.
④ The cooling time is determined according to the cooling channel layout and product thickness, and is initially set at 15-20s.
⑤ Manually start the injection process, improve or reduce the relevant data according to the defects of the injection products, until the product quality meets the requirements, and allow continuous operation.Pvc Vertical Injection Moulding Machine.
⑥ Switch the machine from manual mode to semi-automatic mode, and adjust the parameters in the production process to achieve the best injection cycle. Injection cycle=mold opening and closing time+injection time+melting time+cooling time,multiplas Vertical Injection Molding Machine. all of which need to be minimized. Generally speaking, for the 100g injection molding machine, if the 2-plate mold is used, the mold opening/closing time will be kept at about 2s, and if there is a slider, it will be appropriately extended. The injection time should be gradually reduced by 0.5 seconds until defects appear. Then stop adjusting and return to the previous data. In terms of melting time, reduce the back pressure as much as possible, accelerate the melting speed, avoid gas mixing and bubbles, etc. The adjustment of cooling time is similar to the adjustment of injection time: gradually reduce 1 s, and then compare the molded product with the standard sample. If the quality of the two is the same, it is considered as the best cooling time.
