Notes on plastic mould


Precautions for plastic mold:

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

Some users in the development of products or trial production of new products, often focus on product development and development at the initial stage, ignoring the communication with plastic mold manufacturers. After the product design scheme is initially determined, contacting the mold manufacturer in advance has two advantages

1. It can ensure that the designed product has a good forming process, and the design will not be modified because the parts are difficult to process.

2. The mold maker can make design preparation in advance to prevent improper consideration in a hurry and affect the construction period.

3. Only with the close cooperation between supply and demand sides, can we finally reduce the cost and shorten the cycle.

2、 Don't just look at the price, but consider from the quality, cycle and service.

1. There are many kinds of molds, which can be roughly divided into ten categories. According to the different requirements of parts material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life and economy, different types of die forming are selected.

2. The die with high precision needs to be processed by high-precision CNC machine tool, and the die material and forming process have strict requirements, and CAD / CAE / CAM die technology is also needed to design and analyze.

3. Due to the special requirements of some parts, the mold also needs to use advanced technology such as hot runner, gas assisted molding, nitrogen cylinder and so on.

4. The manufacturer shall be equipped with CNC, EDM, WEDM and NC profiling milling equipment, high-precision grinder, high-precision CMM, computer design and relevant software.

5. Generally, large stamping dies (such as automobile cover parts mould) should consider whether the machine tool has blank holder mechanism, or even edge lubricant, multi position progressive, etc. In addition to stamping tonnage, punching times, feeding device, machine tool and die protection device should be considered.

6. The above mold manufacturing means and technology are not owned and mastered by every enterprise. When choosing a cooperative manufacturer, we must understand its processing ability, not only depending on the hardware equipment, but also combining the management level, processing experience and technical strength.

7. For the same set of mould, there is sometimes a big gap between quotations from different manufacturers. You should not pay more than the value of the mold, at the same time, should not be less than the cost of the mold. Mold manufacturers like you, to make a reasonable profit in the business. Ordering a set of molds with a much lower price would be the beginning of trouble. Users should start from their own requirements and comprehensively measure.

3、 Avoid multi cooperation, try to make plastic mold and product processing in a one-stop way.

1. With the qualified mold (the test piece is qualified), the batch of qualified products may not be produced. This is mainly related to the machine tool selection, forming process (forming temperature, forming time, etc.) and the technical quality of the operator.

2. With a good mold, but also have good forming processing, the best is a one-stop cooperation, try to avoid multi cooperation. If the conditions are not met, one party should be fully responsible for the contract, and it must be written clearly at the same time.
