The various tools and products we use in our daily production and life, from the base and shell of machine tools to the shell of various household appliances, are all closely related to molds. The shape of the mold determines the appearance of these products, and the processing quality and accuracy of the mold also determine the quality of these products. Due to the different materials, appearances, specifications, and uses of various products, molds are divided into non plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds. What should we pay attention to in order to ensure the manufacturing effect of plastic molds? Below, Shenzhen Plastic Mold Factory will explain the three major precautions for plastic mold manufacturing.

1、 Don't just focus on product design and ignore plastic mold manufacturing.

Some users often focus only on product development and trial production in the early stages, neglecting communication with plastic mold making units. After the preliminary determination of the product design plan, there are two benefits to contacting the mold manufacturer in advance:

1. It can ensure that the designed product has good forming technology and will not be modified due to difficulty in processing parts.

2. Mold makers can make design preparations in advance to prevent hasty and inadequate consideration, which may affect the project schedule.

3. Producing high-quality plastic molds requires close cooperation between supply and demand to ultimately reduce costs and shorten cycles.

2、 Don't just focus on price, consider quality, lead time, and service comprehensively.

1. There are many types of molds, which can be roughly divided into ten categories. Select different types of molds for forming based on different requirements such as part materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface smoothness, service life, and economy.

2. High precision molds require the use of high-precision CNC machine tools for processing, and there are strict requirements for mold materials and forming processes. CAD/CAE/CAM mold technology is also needed for design and analysis.

3. Some parts have special requirements during molding, and advanced processes such as hot runner, gas assisted molding, and nitrogen cylinder are required for the mold.

4. Manufacturers should have CNC, EDM, wire cutting machine tools and CNC imitation milling equipment, high-precision grinding machines, high-precision coordinate measuring instruments, computer design and related software, etc.

5. Generally, for large stamping molds (such as automotive cover molds), it is necessary to consider whether the machine tool has an edge pressing mechanism, even edge lubricants, and multi station advancement. In addition to stamping tonnage, consideration should also be given to punching times, feeding devices, machine tools, and mold protection devices.

6. The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When choosing a collaborative manufacturer, it is important to understand its processing capabilities, not only in terms of hardware equipment, but also in combination with management level, processing experience, and technical strength.

7. There may be significant differences in quotes from different manufacturers for the same set of molds. You should not pay more than the value of the mold, nor should you pay less than the cost of the mold. Mold manufacturers, like you, need to achieve reasonable profits in their business. Customizing a much lower priced mold would be a troublesome start. Users must start from their own requirements and comprehensively evaluate.

3、 Avoid multi head collaboration and try to integrate plastic mold production and product processing as much as possible

1. With qualified molds (qualified specimens), it may not be possible to produce batches of qualified products. This is mainly related to the selection of machining machines for parts, forming processes (forming temperature, forming time, etc.), and the technical quality of operators.

2. With good molds, there should also be good forming and processing. It is best to have a one-stop collaboration and avoid multi head collaboration as much as possible. If the conditions are not met, it is necessary to choose one party to take full responsibility and clearly state it when signing the contract.
