All kinds of tools and products used in our daily production and life, as large as the base of the machine tool, the body shell, as small as a blank head screw, buttons and the shell of various household appliances, are closely related to the mold. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Because of the different materials, appearance, specifications and uses of various products, molds are divided into casting molds, forging molds, die-casting molds, stamping molds and other non-plastic molds, as well as plastic molds. In order to ensure the manufacturing effect of plastic molds, what should we pay attention to? The following Shenzhen plastic mold factory will tell you about the three major precautions for plastic mold manufacturing.

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

Some users in the development of products or new product trial production, often only focus on the initial product development and development, ignoring the communication with plastic mold manufacturing units. After the product design scheme is preliminarily determined, there are two advantages to contacting the mold manufacturer in advance:

1, can ensure that the design of the product has a good forming process, not because the parts are difficult to process and modify the design.

2, mold makers can make design preparations in advance to prevent ill-considered in a hurry, affecting the construction period.

3, the production of high-quality plastic molds, only the supply and demand sides closely cooperate, in order to ultimately reduce the cost, shorten the cycle.

Second, do not only look at the price, but also consider the quality, cycle and service.

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

2, the mold with high precision requirements needs to use high-precision CNC machine tool processing, and the mold material and forming process have strict requirements, but also need to use CAD/CAE/CAM mold technology to design and analyze.

3, some parts due to the special requirements of molding, mold also need to use hot runner, gas-assisted molding, nitrogen cylinder and other advanced technology.

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

5, the general large stamping die (such as the car cover die) to consider whether the machine tool has a holding mechanism, and even edge lubricants, multi-station progressive. In addition to the stamping tonnage, it is also necessary to consider the stroke, feeding device, machine tool and die protection device.

6. The manufacturing means and process of the above-mentioned mold are not possessed and mastered by every enterprise. When choosing a cooperative manufacturer, we must understand its processing capacity, not only to see the hardware equipment, but also to combine the management level, processing experience and technical strength.

7, for the same set of molds, the price of different manufacturers sometimes has a big gap. You should not pay more than the cost of the mold value, nor should you pay less than the cost of the mold. Mold manufacturers, like you, want to make reasonable profits in their business. To order a set of molds with a much lower price would be the beginning of trouble. Users must start from their own requirements, comprehensive measurement.

Three, avoid multi-head collaboration, as far as possible plastic mold production and product processing one-stop

1, with a qualified mold (specimen qualified), may not be able to produce a batch of qualified products. This is mainly related to the selection of the machining machine tool, the forming process (forming temperature, forming time, etc.) and the technical quality of the operator.

2, with a good mold, but also have a good forming processing, it is best to one-stop cooperation, try to avoid multi-head collaboration. If the conditions do not meet, it is necessary to choose a party to be fully responsible, and be sure to write clearly when signing the contract.
