At present, plastic mold has become the most common item in people's daily life. After 20 years of development, the quality of mold has always been in the forefront of the world. The plastic mold of many manufacturers has a bad phenomenon, and the reasons are complex, including mold and process conditions. The two are often handed over together.


Although the plastic mold design is carried out under the expected process conditions when the molding materials and equipment are selected, people's understanding is often incomplete. Therefore, the mold test must be carried out after the completion of the plastic mold processing to see how the molded parts quality is. After the problems are found, the mold repair should be carried out to eliminate errors.


Before plastic mold repair, it is necessary to carefully analyze and study the defective plastic parts according to the actual situation of the plastic parts, find out the causes of the plastic parts defects, and then propose remedial measures. Because the forming conditions are easy to change, the general practice is to change the forming conditions first, and repair the mold only when changing the forming conditions can not solve the problem.


The strict quality control procedure, from the raw materials of plastic molds to the final delivery, strictly controls each link, so that the rationality of plastic mold design, manufacturing accuracy, mold life and injection product quality meet your requirements, and produce high-quality plastic molds and plastic mold injection products for you.

In the plastic mold manufacturing process, various factors can affect the quality of the final product. Sometimes, even after adjusting the forming conditions, some problems may persist, and the quality of the product may still not meet the desired standards. In such cases, it may be necessary to consider repairing the mold.

Mold repair is the process of fixing any defects or damage in the mold to ensure that it functions correctly during the plastic molding process. The repair process can involve various techniques, depending on the type and extent of the damage to the mold.

When to Consider Mold Repair

If you experience any of the following problems during the plastic molding process, it may be time to consider repairing the mold:

  1. Surface defects: If the final product has surface defects such as scratches, dents, or cracks, it could be due to issues with the mold surface. Repairing the surface of the mold can help eliminate these defects.
  2. Warping: Warping is a common problem in plastic molding and can be caused by various factors such as cooling rate, material shrinkage, and uneven wall thickness. If you notice warping in the final product, repairing the mold can help solve the problem.
  3. Flashing: Flashing is the excess material that flows out of the mold cavity during the molding process. It can be caused by various factors such as excessive injection pressure, low clamping force, or incorrect alignment of the mold. Repairing the mold can help eliminate flashing issues.
  4. Inconsistent dimensions: If the final product has inconsistent dimensions, it could be due to issues with the mold's design or construction. Repairing the mold can help ensure that the dimensions of the product are consistent.

Mold repair can help extend the life of the mold and save money by avoiding the need for a new mold. However, it is important to note that mold repair is not always a viable option, and sometimes a new mold may be necessary.

In conclusion, mold repair is an essential part of the plastic molding process. When forming conditions cannot solve the problem, repairing the mold can help eliminate various defects and ensure that the final product meets the desired standards. By understanding when to consider mold repair and the different techniques involved, manufacturers can produce high-quality products and minimize downtime.
