Development of high performance plastic rubber machinery in Taiwan
At the 2007 Taipei International Rubber and Plastics Industry Exhibition, Hu Yongjin, the convener of the Plastics Machinery Professional Committee of Taiwan Machinery Association, and the chairman of Baisu Enterprise, bluntly said that under the pressure of recession, Taiwan's injection molding machines have created high-performance models. Research and development.
Taichung Seiki introduced an electric hybrid injection molding machine based on servo control.
Va-150-Hybrid. The difference between this machine and the traditional oil-electric composite injection molding machine lies in the fact that the former has the characteristics of energy-saving, fast and stable all-electric injection molding machine, and is supplemented by an accumulator to store oil pressure energy, so that the injection speed can reach 1200 mm/ Seconds to minimize energy consumption. This machine is especially suitable for the production of high viscosity or thin meat plastic products such as memory cards, IC cards, battery boxes, etc. in the computer, telecommunications and electronics industries.
The high-speed injection molding machine launched by Bai Plastic has an injection speed of 1500 mm/s, and the product quality is good. The PC card housing card produced at the exhibition site will not break even if it is bent strongly. The main reason is The design of the pressure system.
The full-bodied CLF-180TX pressure-retaining multi-circuit was developed to shorten the processing time and reduce the production cost. For example, a PET preform with a diameter of 32 mm and a weight of 75 g, a cavity of 1 mode and 48 cavities, and a cycle time of only 28 seconds. .
Nanxun has developed a BMC (Block Molding Plastic) injection molding machine, which is reported to be half the price cheaper than similar foreign models. There is also a double-stencil die-molding machine with a new clamping mechanism that contains only two templates, so the machine can be shortened by 30% and the machine is lighter, which helps reduce the investment cost of the plant.
In terms of two-color and multi-color molding machines, Quan Lifa, Baisu, Nanxun and Zhenxiong have products. Among them, Nanxun's TNRX-230 two-color machine adopts a fixed mold base and a replacement mold core. Since only the mold core is replaced, the mold cost can be reduced, and the Lai Sheng wins less than the traditional one-third. As for the Zhenxiong direct pressure two-color injection molding machine, the two plates have a reciprocating 180-degree rotating turntable, which can be used with a set of two-color molds, or
Two sets of molds for double/two-color injection molding.
As for the all-electric injection molding machine, many manufacturers such as Taichung Seiki, Zhenxiong and Qunji have exhibited. It is reported that the Taiwan area has established an all-electric injection molding machine R & D alliance. Wang Zhengqing, deputy director general of the Taiwan Machine Industry Association, expects that all-electric injection molding machines with high injection speed, low injection power, low forming cycle, energy saving, clean, low noise and easy maintenance will be widely used in computers, electronics, High value-added industries such as telecommunications, medical equipment, and precision machinery.
Drilling Rig is the main rig equipment, the range of Drilling rig accessories is very widely. Such as Traveling block, Crown Block, Hooks and Swivel. These four equipments are all belong to the Hoisting System of drilling rig. Usually, the eight big rig equipments include : Derrick, Crown Block, Drawworks , Traveling block, Rotary Table, Hooks, Swivel and Drilling Mud Pump.
