Compared with other molds, the tpu injection mold structure is more complicated and more precise, and requires higher operation and maintenance of the product. Therefore, in the entire production process, the correct use of the solution, careful maintenance and maintenance, maintaining the normal production of the enterprise, and improving the efficiency of the enterprise, is of great significance.
First, select the appropriate molding equipment, determine the reasonable process conditions, if the injection molding machine is too small, it can not meet the requirements, too much is a waste of energy, and will damage the mold or template clamping force due to improper adjustment, while reducing efficiency.
When selecting the injection molding machine, the maximum injection quantity, the effective distance of the tie rod, the installation size of the tpu injection mold on the template, the maximum mold thickness, the minimum mold thickness, the template stroke, the injection mode, the injection stroke, the injection pressure, the clamping force, and the like. Verification, can be used after the request is sufficient. Reasonable determination of the process conditions is also one of the reasons for the correct use of the mold, excessive clamping force, excessive injection pressure, too fast injection speed, high mold temperature, etc., which will damage the service life of the mold.

Maintenance recommendations for injection molds
Second, after installing the mold on the injection molding machine, the empty mold must be operated first. Observe whether the operation of each component is flexible, whether there is an abnormal phenomenon, the ejection stroke, whether the opening stroke is in place, whether the parting surface is closely matched when the mold is closed, and whether the platen screw is tightened.
Third, when using the mold, it must be kept at room temperature and work at room temperature to extend the service life of the tpu injection mold.
Fourth, the sliding parts on the mold, such as the guide post, return needle, push rod, core, etc., should be observed at any time, regular inspection, timely scrubbing and filling grease, especially in summer, high temperature, at least twice per shift, to Make sure these sliders are flexible to prevent stressful seizures.
