Three major considerations in plastic injection mold making, ignoring a will be scrapped

A, not only heavy product design, ignore the plastic mold manufacturing.
some users in product development or new product trial production, often only focus on product research and development, the early neglect unit of plastic injection mold making and communication. After the product design plan is determined primarily, the early contact with the mould manufacturer has two advantages:
1, the product can protect does design have good forming process, will not modify design type by parts difficult to machining.
2, mold production design to prepare ahead of time, to prevent the thoughtless haste, affect the construction period.
3 and production of high quality plastic moulds, and only the supply and demand both sides closely, can eventually reduce costs, shorten the cycle.
2, don't only look at price, quality, cycle, service comprehensive consideration.
1, there are many kinds of mould, can be roughly divided into 10 categories. According to the parts material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, different requirements, such as service life and economy to select different types of die forming.
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, because some parts have special requirements, still need to use hot runner mold, gas-assisted molding, nitrogen gas cylinder and other advanced technology.
4, manufacturers should have CNC, edm, line cutting machine tools and CNC profile milling equipment, high-precision grinding machine, high precision three coordinates measuring instrument, computer and related software, etc.
5, large stamping die (commonly Such as automobile cover parts die) Want to consider machine if there is a blank holder mechanism, even boundary lubricant, multi-station progressive, etc. In addition to stamping tonnage consider speed, feeding device, machine tool and die protection device.
6, the mould manufacturing method and process and not every enterprise has to master. When choosing cooperation manufacturer must understand its processing capacity, not only see the hardware devices, combine the management level, processing experience and technical strength.
7, for the same set of mold, different manufacturers offer sometimes there is a big gap. You shouldn't pay is higher than the value of mould cost at the same time, also should not be less than the cost of the mold. Mould manufacturer like you, want to get reasonable profit in the business. Ordering a set of quotation is much lower mould will be the beginning of the trouble. Users must be from their own requirements, comprehensive measure.
3, avoid long collaboration, as far as possible plastic mould and products processing one-stop
1, a qualified mould ( Specimen qualified) , may not be able to produce a batch of qualified products. This is mainly with the components of the machine tool selection, forming technology ( The forming temperature and forming time, etc. ) And the quality of operator technique.
2, with a good mold, but also has good forming, had better be a dragon collaboration, try to avoid long collaboration. If the condition does not have, be about to choose one party will be entirely responsible for, in order when the contract must be made clear.
