A, different materials
1, mold
Molds in addition to itself, but also need to mold base, mold frame, mold core lead to the ejection device, these parts are generally made of universal type. Mould enterprises need to be bigger and better, according to market demand, and technology, capital, equipment and other conditions, to determine the product positioning and market positioning, these practices are especially worth learning and reference to small mold enterprises, focusing on gradually forming their own technological advantages and product advantages.
2, hand plate
1) ABS (domestic, imported, transparent, black, ultra-high temperature, etc.)
2) 475 adhesive board, Bakelite, Plastic King and so on.
3) POM (Sai Steel), PMMA (Acrylic), PC, PP, PA, BT, PVC and so on.
4) Aluminum, copper, other types of alloys.
Two, different classifications
1, mold
Hardware molds are divided into: including stamping dies (such as punching dies, bending dies, deep drawing dies, turning hole molds, shrinkage molds, undulating molds, expansion molds, shaping molds, etc.), forging dies (such as die forging die, upsetting forging die, etc.), extrusion molds, extrusion molds, die casting molds, forging molds, etc.
2, Hand plate
1) Appearance of the hand plate: the main test of the product's appearance design, the requirements of the appearance of fine, accurate color, the internal processing requirements are not high.
2) structure of the board: the main test of the structure of the product reasonableness, for the size of the requirements of the higher, the appearance of the requirements of the relatively low, the requirements of foreign countries on this kind of particularly strict.
3) function of the board: the requirements to achieve the same appearance as the real product, structure and function, can be understood as a finished product is not on the market, is the highest requirements, the most difficult category of the board.
Three, the production process is different
1, mold
1) mold production planning and scheduling arrangements (Production Planning and Schedule Arrangement): this stage needs to be for the delivery of the mold to the customer to respond to the specific date.
2) mold design (Design): the possible use of design software Pro/Engineer, UG, Solidworks, AutoCAD, CATIA, etc.
3) mold processing (Machining): the processes involved are roughly car, gong (milling), heat treatment, grinding, computerized gong (CNC), Electric discharge (EDM), wire cutting (WEDM), coordinate grinding (JIG GRINGING), laser engraving, polishing and so on.
2, the board
1) check the appearance of the design
The board is not only visual, but also touchable, he can be very intuitive in the form of physical designers to reflect the creativity out, to avoid the drawings out of the good-looking and made out of the disadvantages of the good-looking. Therefore, the hand plate production in the development of new products, product shape is essential to the process of speculation.
2) Check the structural design
Because the board can be assembled, so it can visually reflect the structure of the reasonable or not, the installation of the degree of difficulty. It is easy to find problems early and solve them.
3) to avoid the risk of directly opening the mold
Because the cost of mold manufacturing is generally very high, relatively large molds worth hundreds of thousands or even millions of dollars, if the process of opening the mold is found to be structurally irrational or other problems, its losses can be imagined. The hand plate production can avoid this loss, reduce the risk of opening the mold.
