The development problems of plastic mould industry

  Our plastic china injection mould development depends on on the development of the plastics industry.Plastic products want to develop, along with the inevitable requirement of plastic mold development. In recent years, automobiles, home appliances, office supplies, industrial appliances, building materials, electronic communications and other plastic are running so rapid, therefore,plastic mold industry growing too.

  The main existing problems through exchanges and cooperation at home and abroad will gradually get a better solution through the joint efforts of the whole industry and joint support from all quarters,  China's plastic mold industry still exists several problems if its development want to catch the foreign advanced level.

1. Unbalanced development and lower overall product level. Although some of the plastic mold company's products have reached a very high level that closing to international standards, but overall, precision mold cavity surface roughness, the production cycle, life expectancy and other indicators comparing foreign advanced level there is a more than 10 years gap.

2. Backward technology and equipment, poor organization and coordination. Although some enterprises have more advanced technology and equipment level through technological innovation. But most companies are still relatively backward technology and equipment. More important is our corporate organization and coordination, it is difficult to integrate or mobilize social resources very well, so it is also difficult to undertake large projects.

3. Most plastic mould enterprise development capacity is weak. On one hand, the low proportion of technical personnel and the level of technical staff is not high enough. On the other hand there is less research and development investment, more important is the idea behind the development is neglected.

4. Management problem is much more than technological backwardness. Technological backwardness is often easy to see, but it is difficult to realize the management problem. The gap between domestic and abroad plastic mold companies is very obvious especially in management.

5. The development of production were unable to keep up with market demands, It’s hard to resolve the contradiction between supply and demand, the supply situation will continue for some time, especially in the High-end products.


SMC mould gets more and more popular in mould making market

SMC mould has a superior corrosion resistance. SMC mould also have other god advantages, such as light weight and easy for engineering design, flexible, etc. The mechanical properties of SMC mould are comparable to part of the metal material. Products made of SMC mould have good rigidity, and is resistance to deformation. What’s more, these goods have a wide temperature range for working. SMC mould is a kind of s flexible material, and has similar performances with metal. So they are widely used in electric meter box mould, auto mould and so on. SMC mould refers to Sheet Moulding Compound. In fact, SMC mould is a kind of glass fiber reinforced thermosetting composites, which are usually made of resin, low shrinkage additive, filler, fiberglass and other sheet material. So SMC mould is suitable for forming. Now due to the production of the enterprise needs, a large number of mold manufacturers use this kind of SMC material to make SMC mould. As the global energy shortage and the development of new energy, lightweighting of vehicle affects another new materials -- FRTP material, made of GMT/LFTD process of fiber reinforced thermoplastic composites (FRTP). Automotive parts and components has been widely developed and gets a large number of applications. No matter SMC/BMC material or GMT/LFTD material, these two kinds of materials’ processing and products have sprung up across the country hundreds of heat mould products and material, mould, auxiliary supporting enterprises, and formed a huge industry group. SMC mould processing gets fast development in recent years. Cheap SMC mould processing products occupies large proportion of glass fiber reinforced plastic molding processing and occupies one third of mechanized molding fiberglass products. SMC mould have a wide application, such as electrical electrical switch, meter boxes, household electrical appliances spare parts, small wind generators and blade head box, assembled truss type whole bathroom, toilet cover, rural buried purification tank, pool, automotive parts, bumper, table tennis, SMC door plank, building stone panel inside and outside decoration and assembled type dustbin, highway use anti-glare board, sound insulation board, motor boats, etc. GMT/SMC/BMC materials, because of its performance, are widely used indifferent fields through the mold processing and injection molding. In recent years, with the development of the market of mould making, a series of process faced with technological innovation. China SMC mould manufacturers should gasp this oppunity of innovation to occupy a larger SMC mould market in the world.
