Solutions to problems encountered during injection molding

Mold management can be roughly divided into three different parts, that is, mold development, mold use and mold maintenance, therefore, effective management of mold, Versella pointed out that we can start from the process to improve the management of each part.

First of all, in mold development, it is necessary to set up a mold development team, appoint project manager, contact person to monitor the whole process of development.

Hold mold development meetings to discuss product characteristics, steel types, mold life, precision requirements, mechanical specifications, the impact of finished product shape on mold, evaluate the development time, etc.; Through the above management methods, enterprises can not only get more accurate evaluation, but also train new employees through mutual communication.

At the same time, enterprises should monitor the actual progress of the project. Such as using project monitoring tools, predict and calculate the actual progress schedule, and compare the actual progress of the project with the planned progress, correct any deviation from the plan, timely make appropriate response to the production of division, such as using different masters in charge of wire cutting, deep hole processing, lathe, polishing, heat treatment, etc.;

This is not only easier to train technical staff, but also do not have to rely on one or two comprehensive technical talent, so that the loss of talent loss is reduced. But in this process, the instructions must be standard and clear. In addition, given the constraints of short lead times, some tasks can be outsourced so that the company can focus its resources on its core work.

Secondly, in the use of the mold, we should pay attention to the extraction, mold test, manufacturing, recycling often encountered difficulties, such as can not find the mold or mold has been damaged can not be used; The mold needs to be repaired after the mold is installed and tested. Manufacturing did not pay attention to the mold life has expired, thus affecting the quality of the product; The status of the used mould is not recorded, which leads to the delay of the production period when it is used again in the future.

For these problems, it is necessary to record the status and information of each use of the mold, because recording the number of stamping of the mold is of great help to evaluate the life of the mold. At the same time, the practice of regular or quota maintenance treatment, depending on the situation to decide whether to repair, provide the mold has been used data, so that customers assess the impact of mold on product quality, decide whether to build new mold.

In addition, it is necessary to unify the management of mold entering and leaving the warehouse. Special personnel should be responsible for borrowing and returning the mold. All the entering and leaving should be recorded and signed for.

Finally, in the maintenance of the mold, for each mold are independent records, mold also have an independent folder (real or electronic file), record all the changes and status, such as the life of the mold, the state of the mold, including abnormal loss of the situation; The mold should also be clearly classified, such as hardware, die-casting, plastic and so on.

In addition, it is necessary to develop a maintenance plan and carry out regular maintenance and management of molds, so as to reduce the risk of damage and reduce maintenance costs.
