Zhende Injection Molding Machine Troubleshooting Guide

： Zhende Injection Moulding Machine Trouble Shooting Guide I. Introduction In order for a plastic injection moulding technician to accurately identify and solve problems on a Zhende injection moulding machine, knowledge of how the machine operates is essential. This guide provides a concise overview of the workings of a Zhende injection moulding machine, as well as useful trouble shooting tips. II. The Basics A Zhende injection moulding machine consists of a clamping unit and an injection unit. The clamping unit is responsible for holding the mould and delivering the part. It consists of 3 main components - the toggle mechanism, a mould platen, and plastic injection cylinder. The injection unit is responsible for injecting molten plastic material into the mould. It consists of 4 main components - a screw, a heating cylinder, a nozzle, and a check valve. The nozzle is connected to a check valve which is responsible for preventing backflow of plastic material when the screw is retracted. The screw is controlled by a servo motor, which is responsible for regulating the speed and amount of plastic material that is injected into the mould. III. Trouble Shooting Tips 1. Clamping Unit Malfunction: Check that all bolts and nuts are tightened properly and that no parts are missing or damaged. Make sure that the mould plate is level and that the toggle mechanism is working properly. 2. Injection Unit Malfunction: Check the nozzle for blockages and make sure that the screw is turning properly. If the screw is not turning properly, check for worn or damaged parts. Also check that the heating cylinder is working properly and that the temperature is correct. 3. Low Quality Parts: Check the mould for any damage or wear. Make sure that the mould is securely mounted and that the clamping force is sufficient. Check the injection parameters to ensure that they are correct. Check that the injection unit is working properly and that the temperature is correct. 4. Shorter Cycle Times: Increase the clamping force to make sure that the mould is securely held in place. Check the injection parameters and adjust accordingly to reduce cycle time. Increase the speed of the screw if possible. IV. Conclusion Following the above tips and guidelines can help improve the performance and reliability of Zhende injection moulding machines and help to ensure that the production process is both efficient and cost-effective. With proper maintenance, a Zhende injection moulding machine can last for many years and provide reliable performance.
