Online Open Week ｜Connects German Technology，The first show of WIT Water Injection Molding Solution

The “Connect China and Europe” project welcomes a new progress. YIZUMI collaborated with PME fluidtec, a German company, to launch the WIT Water Injection Molding Solution, which will be displayed on the Online Open Week held in Wujiang factory. It will produce two-color wheel on site.

Water Injection Technology refers to: the injection molding machine injects liquid under high pressure into the product at the moment of injection completion to create a hydraulic cavity inside the product. After the completion of the molding, the fluid is discharged and a hollow is created. WIT reduces product weight, eliminates internal stress, and effectively lowers product's demand for clamping force. Compared with gas injection molding (GIM), WIT is more stable with better cooling effect. It renders cycle time saving to a certain extent and brings more benefits to products with thicker wall.

Based on the UN500D1 two-platen injection molding machine and PME fluidtec water-assisted machine, the WIT Water Injection Molding Solution shown on the Online Open Week will produce wheel composed of three parts. The injection molding machine completes one of the three parts of wheel hub and wheel each time. The wheel hub is completed with direct injection of PP with 50% glass fiber, the robot will extract the wheel hub and embed it into the wheel mold as the core for second injection with ordinary PP. A hollow is created in the wheel through water injection process.

Through water injection technology, the product does not have an overflow slot as excess plastic is pushed back into the barrel of injection molding machine for the next injection. Combined with the use of the hot runner, the entire production process causes no material waste and reduces the product stress effectively, resulting in better dimensional stability.

This WIT Water Injection Molding solution can be used for lightweight products in the automotive industry, such as thick-walled plastic decorative parts, automotive cooling water pipe, luggage-rack, and seat, besides, in the logistics industry, manufacturing products such as the handles of hand trucks and the frames of turnover boxes. It can also be used in the furniture industry for certain thick-walled parts such as table legs.
