First, some users in the development of products or new products trial production, often only focus on product development and development at the beginning, ignoring the communication with the mold production unit. After the product design plan is initially determined, there are two advantages to contacting the mold manufacturer in advance:
(1) It can guarantee that the designed product has a good forming process, and will not modify the stereotyped design because the parts are difficult to process.
(2) The mold maker can make design preparations in advance to prevent inconsistency in the rush and affect the construction period.
In short, to produce high-quality molds, only the close cooperation between the supply and demand sides can ultimately reduce the cost and shorten the cycle.
Second, don't just look at the price, we must consider all aspects of quality, cycle and service.
There are many types of molds, which can be roughly divided into ten categories. According to different requirements of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., different types of mold forming are selected.
Molds with high precision requirements need to use high-precision CNC machine tools, and the mold materials and forming processes have strict requirements. They also need to use CaD/CaE/CaM mold technology to design and analyze. Some parts have special requirements for molding, and the mold also needs to use hot runners and gas-assisted molding. Manufacturers should have CNC, EDM, wire cutting machine tools and CNC copy milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer design and related software. Generally, large-scale stamping dies (such as automobile cover molds) should consider whether the machine has a crimping mechanism, or even a lubricant, a multi-function level. In addition to punching tonnage, it is necessary to consider the punching, feeding device, machine tool and mold protection device.
The manufacturing methods and processes of the above molds are not available and grasped by every enterprise. When choosing a collaborative manufacturer, you must understand its processing capabilities, not only to look at hardware equipment, but also to combine governance, processing experience and technical strength. For the same set of molds, there are sometimes large gaps in the prices of different manufacturers. You should not pay more than the cost of the mold, and should not be less than the cost of the mold. Mold manufacturers, like you, have to make a fair profit in the business. Ordering a set of molds with much lower quotations can be a hassle to start. Users must proceed from their own requirements and comprehensively measure them. A much lower mold can be a troublesome start. Users must proceed from their own requirements and comprehensively measure them.
Third, avoid multi-headed collaboration, try to make mold and product processing one-stop.
