Make a bit experience of the mould for years

The · of a few problems that the mould that make needs to notice does not weigh products plan only, negligence mould makes some users be when development product or new product trial-produce, often initial stage notes overweight product development and development only, negligence and mould make the communication of the unit. After products plan plan is preliminary and definite, have two profit with die manufacturer contact ahead of schedule namely: One, the figuration craft that can make sure the product of the design has had, won't be machined hard because of the spare parts and modify modular design. 2, the mould is made just can make design preparation ahead of schedule, the consideration in preventing haste not, influence time limit for a project. Anyhow, mould of the high quality that make, only both sides of supply and demand cooperates cheek by jowl, ability reduces cost finally, shorten periodic. · does not see the value only, want from quality, periodic, service all-around consideration mould is a lot of more phyletic, can divide roughly it is 10 kinds big. The basis is hardware data, physico-chemical function, mechanical precision of intensity, dimension, surface is bright and clean degree, the diverse demand such as service life, economy, choose the mould take shape of different type. Precision asks the numerical control machine tool that tall mould needs to use high accuracy is machined, and craft of qualitative, figuration has mould material to ask strictly, still need to use CAD/CAE/CAM mould technology to go design, analysis. Because some spare partses shape from time to tome special requirement, the mould still needs to use hot flow path, gas complementary shape, the advanced technology such as nitrogen crock. Manufactory home should have facility of machine tool of cut of numerical control, electric spark, line and numerical control copy mill, high accuracy grinder, high accuracy 3 coordinate measuring instrument, computer design and relevant software. Mould of general and large punch (if car answer builds a pattern) should consider a machine tool to whether have the orgnaization that approach a limit, even edge lubricant, multitask class is entered etc. Consider to rush even except punch tonnage second, send makings device, machine tool and mould protector. Every enterprise is had and the production method of afore-mentioned moulds and craft do not master. Its process capability must understand when choosing synergic manufacturer, not only visit hardware facility, join experience of level of management, treatment and technical force even. Right same cover a mould, different manufacturer quoted price has very big difference sometimes. While you ought not to pay fee of value of prep above mould, also not should little the cost at the mould. Die manufacturer resembles you same, want to gain reasonable profit in business. Order control a quoted price so low that much mould meets be a trouble begin. The user must ask to set out from oneself, measure in the round. · prevents bull cooperation, as far as possible the pattern that the mould is made and goods treatment one continuous line had qualification (test specimen is eligible) , can not produce the eligible product that gives lot certainly. This is main craft of the type selecting of treatment machine tool with the spare parts, figuration (time of figuration temperature, figuration) the technical quality that reachs handlers is relative. Had good pattern, have good form cutting even, had better be cooperation of one continuous line, prevent bull cooperation as far as possible. If the condition is not had, be about to choose one party to be in charge of in the round, it is clear to must be written when concluding a contract. Http://info.
