1. some users in the development of products or new product trial, often the initial focus on product development and development, ignoring the communication with the plastic mold production unit. After the product planning program begins to confirm, that is, early contact with the mold manufacturer has two advantages:

1, can ensure that the planned product has a good forming process, will not be difficult to process parts and modify the stereotypes planning.

2, mold production can make planning preparation in advance, to prevent hasty consideration, affect the construction period.

3, the production of high-quality plastic mold, as long as the supply and demand sides closely cooperate, the ability to ultimately reduce costs, shorten the cycle.

2. don't just look at the price, from the quality, cycle, service all-round consideration.

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

2. Mould with high precision requirements needs to be processed by high-precision numerical control machine tools, and there are strict requirements for mould raw materials and forming process. CAD / CAE / CAM mould skills are also needed to plan and analyze.

3. Some parts have special requirements for molding, and the mold also needs to use advanced technologies such as warm flow channel, gas assisted molding, nitrogen cylinder, etc.

4, the manufacturer should have CNC, EDM, wire cutting machine and CNC copying milling equipment, high-precision grinding machine, high-precision three-coordinate measuring instrument, computer planning and related software.

5. Generally, large stamping dies (such as automobile cover dies) should consider whether the machine tool has edge pressing organization, even edge lubricant, multi-station progressive, etc. In addition to stamping tonnage, punching times, feeding equipment, machine tools and mold protection equipment should also be considered.

6, the above-mentioned mold production methods and processes are not every enterprise has and grasp. In the selection of cooperative manufacturers must understand its processing capacity, not only look at the hardware equipment, but also combined with the management level, processing experience and skills.

For the same set of molds, there is sometimes a big gap between the quotations of different manufacturers. You should not pay more than the cost of the mold together, nor should you pay less than the cost of the mold. Mold manufacturers like you, to make a reasonable profit in the transaction. Ordering a set of molds with a much lower quotation would be the beginning of the trouble. Users must start from their own requirements, comprehensive measurement.

3. prevent multi-head collaboration, as far as possible plastic mold production and product processing one-stop.

1, with a qualified mold (test piece qualified), may not be able to produce a batch of qualified products. This is mainly related to the selection of machine tools, forming process (forming temperature, forming time, etc.) and the nature of the operator's skills.

2, with a good mold, but also a good forming process, it is best to one-stop cooperation, as far as possible to prevent multi-head cooperation. If the conditions are not met, one party must be selected to take the overall position, and it must be clearly written together.
