Application of laser cutting machine

Laser cutting machine is that the energy of the laser beam is irradiated on the surface of the workpiece so that the workpiece is released to melt and evaporate, has the purpose of cutting and carving. It is the use emitted from the laser light generator, a laser beam is focused by the optical system into a high-power density laser beam irradiation conditions, the laser heat is absorbed by the material of the workpiece, a sharp rise in temperature of the workpiece, after reaching the boiling point, the material starts to vaporize and the formation of holes, with the high pressure gas stream, with the movement of the relative position of the beam and the workpiece, the material eventually forming the slits. Laser cutting machine as a new tool to use increasingly sophisticated variety of industries, including laser cutting machine, laser engraving machine, laser marking machine, laser welding machine.

Metal laser cutting machine is the use of high power density laser beam scans over the surface of the material, the material is heated in a very short time first million to several thousand degrees Celsius, melting or vaporization of the material, and then the high pressure gas from the molten or vaporized material cut seam blown away, to achieve the purpose of cutting material. Laser cutting, since the beam is not visible instead of the traditional mechanical knife, mechanical portion of the laser head without contact with the work, the work will not cause scratches on the surface of the work; Laser cutting speed, smooth incision, usually without subsequent processing; small cut heat-affected zone, the plate deformation is small, narrow kerf (0.1mm ~ 0.3mm); incision without mechanical stress, no cutting burr; high precision, repeatability, does not damage the material surface; CNC programming, processed any plan, you can format the entire board cut great, no open mold, economic saving. Metal laser cutting machine advantages: high accuracy; speed; small heat-affected zone, not easily deformed; high cost; low cost; ongoing maintenance costs low; stable performance, maintain continuous production.

Development of the laser industry, although a preliminary development, but in the international science and technology led to the development leap has been completed, and the same quality with outstanding than a high stage. Laser cutting machine in terms of market demand up to ten million, for a broad market added new vitality. Since the birth of the first laser devices and applications since the 1960s, China had a number of experts in the laser industry made efforts, and to the international one tiny difference. The rapid development of the domestic economy, has become a pillar industry of high laser market, and can reach more than 20% annual growth rate, as a new starting point for the global laser market, according to experts predict that the domestic market is still in laser rapid growth phase, You can double the increase during the next to the largest expansion of laser cutting equipment market, to fill the gaps, the domestic high-end laser equipment to get rid of the troubled state, becoming the mainstay of the international community.

Plastic mold design issues to be considered

Plastic mould, plastic processing industry and plastic molding machine supporting, giving plastic products in order to complete configuration and the exact size of the tool. Because many plastic varieties and processing methods, structural plastic moulding machine and plastic products and Traditional and Simplified different, so the type and structure of the plastic mould is varied. Plastic mould is a tool for the production of plastic products which parts parts by several groups, this combination successful mold cavity. When injection moulding, the injection moulding machine mold clamping, the molten plastic is injected into the mold cavity, and cooled in the cavity shape, and then the upper and lower split mold through the top of the article from the mold will leave the top of the mold cavity, the mold is closed again and finally for the next injection, the whole cycle of the injection molding process is carried out. Precision plastic mold design needs to consider the following questions:
1 understand the plastic melt flow behavior, consider the plastic resistance in the flow channel and the cavity of each flow, flow rate, parity maximum flow length. According to plastic flow direction in the mould (ie filling the order), consider the plastic in the mould re-fusing the inner cavity of the original air and export problems.
2 Consider plastic shrink during cooling and feeding problems.
Adoption of plastic mould design to control crystallization in the mold. Orientation and improve internal stress products.
4 Select the problems pouring into parting
Lateral type 5 and the top parts of the core pulling out of the question.
Cooling or heating problems 6. mold.
7 related to the size of the relationship between mold injection machine with the relationship, including the maximum injection volume and injection machines. Clamping force. Dimensions Die parts, etc..
8 Die overall structure and shape of the part to be simple and reasonable, the mold should have the appropriate accuracy. Finish. Strength and stiffness, easy to manufacture and assemble
With the rapid development of plastics and plastic moulding industry, plastic mould also emerged at this time, and now for the quality requirements of the plastic moulds are also increasing, which is the development of plastic mould industry offers tremendous momentum. Restructuring plastic mold industry continues to accelerate, market-oriented professional manufacturer of plastic mould number and ability to grow very fast. According to the production, sales, market conditions, industry structure, product import and export, etc. plastic mold manufacturing industry analysis, reference plastic mold-related industry trends, future development of plastic mould manufacturing industry is very broad.
