Injection moulds must bear in mind three key points of plastic moulds

               Injection moulds must bear in mind three key points of plastic moulds

   Plastic moulds are applied more and more widely in industrial production and processing, and play a bigger role, and the production demand is more and more. Therefore, in the process of making plastic moulds, attention should be paid to improving the production efficiency.The following three points should be noted in making plastic mold:

   First, do not only focus on product design, ignore plastic mold manufacturing.

   When some users develop products or try out new products, they often pay attention to product development and development at the initial stage, and neglect the communication with the plastic mold making unit.After the product design scheme is preliminarily determined, it has two benefits to contact the mold manufacturer in advance:

1. It can guarantee that the designed product has a good forming process and will not modify the shaping design due to the difficulty of parts processing.

2. The mold making can prepare the design in advance, so as to avoid improper consideration in a hurry and affect the construction period.

3. Make high-quality plastic molds. Only when the supply and demand sides cooperate closely can the cost and cycle be reduced finally.

   Second, do not only look at the price, from the quality, the cycle, the service all-round consideration.

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

2. The mold with high precision needs to be processed by high-precision CNC machine tools. Besides, the mold material and forming process have strict requirements.

3. As some parts have special requirements when forming, the mold shall also use advanced technologies such as heat flow channel, gas-assisted molding and nitrogen cylinder.

4. The manufacturer should be equipped with CNC, edm, linear cutting machine and nc copy milling equipment, high-precision grinding machine, high-precision three-coordinate measuring instrument, computer design and related software.

5. Generally large stamping dies (such as automobile cover mold) should consider whether the machine tool has edge press mechanism, even lubricant, multi-station progressive, etc.In addition to the stamping tonnage also consider punching, feeding device, machine tool and die protection device.Exchange of plastic knowledge WeChat group plus small WeChat: NB58250988

6. The manufacturing method and process of the above moulds are not available and mastered by every enterprise.When choosing cooperative manufacturers, we must understand their processing capacity, not only look at the hardware equipment, but also combine the management level, processing experience and technical strength.

7. For the same set of molds, prices from different manufacturers sometimes differ greatly.You should not pay more than the cost of the mold, nor less than the cost of the mold.The mold maker, like you, wants to make a reasonable profit in the business.Ordering a set of much cheaper moulds would be the start of trouble.Users have to start from their own requirements, comprehensive measurement.

   Third, avoid multi-head cooperation, as far as possible plastic mold production and product processing through - train.

1. With qualified molds (qualified specimens), qualified products may not be produced in batches.This is mainly related to the selection of machine tools, forming process (forming temperature, forming time, etc.) and the technical quality of the operator.

2. With a good mold and a good forming process, it is better to cooperate by a dragon and avoid multi-head cooperation as much as possible.If the conditions are not met, it is necessary to choose a party fully responsible, in the contract must be clearly written.
