Attention points for making plastic molds (2):
Don't just look at the price, consider the quality, the cycle, the service.
1. There are many types of mold, which can be 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 mold forming are selected.
2, high accuracy requirement of mold need to use high precision numerical control machine, and mold material and forming technology has strict requirements, also need to use mould CAD/CAE/CAM technology to design and analysis.
3. Some parts have special requirements due to the molding, and the mold needs to use hot runner, gas-assisted molding, nitrogen cylinder and other advanced technologies.
4. The manufacturer shall be equipped with numerical control, electric spark, wire-cutting machine tool and CNC copy milling equipment, high precision grinding machine, high precision three-coordinate measuring instrument, computer design and related software, etc.
5. General large stamping tools (such as automobile cover mould) should consider whether the machine tool has the pressing mechanism, even the side lubricant, the multi-station step, etc.In addition to the stamping tonnage, we should also consider the charge of punching, feeding device, machine tool and die protection device.
6. The manufacturing means and technology of the above mould are not available and mastered by every enterprise.When choosing a cooperative manufacturer, we must understand its processing ability, not only the hardware equipment, but also the management level, processing experience and technical force.
7. For the same set of molds, the quotation of different manufacturers sometimes varies greatly.You should not pay more than the mold value, and should not be less than the cost of the mold.Mold manufacturers, like you, should make reasonable profit in the business.It would be troublesome to order a set of molds with a much lower price.Users must start from their own requirements, comprehensive measurement.
