When choosing an injection molding machine, the maximum injection volume, the effective distance of the pull 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, etc. should be carried out. Validation, which 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, the clamping force is too large, the injection pressure is too high, the injection speed is too fast, the mold temperature is too high, etc., which will damage the service life of the mold.
1. Select the appropriate molding equipment and determine the reasonable process conditions. If the injection molding machine is too small, it cannot meet the requirements. Too much energy is wasted, and the mold or template clamping force will be damaged due to improper adjustment, and the efficiency will be reduced at the same time.

Maintenance recommendations for injection molds
Second, after the mold is installed on the injection molding machine, the empty mold must be operated first. Observe whether the operation of each part is flexible, whether there is an abnormal phenomenon, whether 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.
3. When using the mold, it must be kept at normal temperature and work at normal temperature to prolong the service life of the tpu injection mold.
4. The sliding parts on the mold, such as guide posts, return needles, push rods, cores, etc., should be observed at any time, checked regularly, scrubbed and filled with grease in time, especially in summer when the temperature is high, at least two secondary oils per shift to avoid Make sure these sliders are flexible to prevent nervous seizures.
