Pvc pipe fitting mould

Ancient Chinese "Sui" appears as an offering to the vine, the Ming Dynasty Masanori years compiled a "positive Jeannet Taiwan Chi" and subsequent "Cliff Chi Chuan" describes the distribution and utilization of rattan. Quanzhou Museum on Zheng He of the Ming Dynasty preserved shipwrecks rattan furniture, these rattan furniture have confirmed the level of development of China at that time. In the existing fine of Ming and Qing furniture, Water purifier molding there are also a rattan chair seat.
According to the Qing dynasty, published "Yongchang government" and "vault hall" records, western Yunnan Tengchong and other places on the use of rattan can be traced back to the Tang Dynasty, to date more than 1500 years of history; in southern Yunnan, according to the Qing " Yuanjiang House "and Republican" Continued New Annals of Yunnan "records, the use of rattan began in the early Qing Dynasty, so far has been 400 years of history. According to the research, Yunnan rattan before World War II have a higher level. At that time, Yunnan rattan exported to Southeast Asia and Germany and other European countries. Yunnan rattan in rattan Tengchong reputation is highest. Rattan style known as the three best Tengchong, Tengchong history books, also known as the vine, Fujikawa, rattan red, thereby glimpsed, Tengchong of rattan, the Great Hall had it as a collection of treasures.

plastic rattan garden furniture mold die manufacturing development trend of the market

In particular, most of the tools is the key part of the plastic rattan garden furniture mold or the member is multi-directional force, thereby increasing the isotropic steel, to improve toughness and ductility lateral, MASTER plastic rattan garden furniture mold can greatly improve the working life of the mold, which is alloy tool steel in recent years, one of the main direction of development. In addition, to improve the purity of the alloy tool steel, alloy tool steel that reduce the content of harmful impurities are effective measures to improve the properties of steel, using a variety of refining process, the production of high purity steel, plastic rattan garden furniture mold steel mills are currently various metallurgical the main direction of efforts. In addition, with the increasingly widespread application of standard mold, plastic rattan garden furniture mold standardization, commercialization of improved quality for steel products, different specifications, and delivery cycles and higher requirements. Therefore, injection moulding companies according to the needs of the domestic iron and steel enterprises mold and die manufacturing development trend of the market, pay close attention to research and development of high-precision, high toughness, corrosion resistance, high-quality new varieties of mold steel, so that made the hot and cold die steel reached the world's.

Plastic rattan garden furniture production process

Plastic raw rattan garden furniture Description: There are two types of stent materials and textile materials.
Bracket material: before MASTER auto mold corrosion, decay, crack and other treatment. In addition to bamboo, but can also be steel, rattan, wicker, plastic and other production bracket.
Woven material: mainly used rattan. Machined into rattan, rattan core and rattan MASTER bathroom mould and other parts for the textile part is Tengpi. There is a wide perception rattan cane, rattan and wild vines and other soil.

Micro-cavity insert manufacturing MASTER plastic rattan molding

Micro-cavity inserts production process as follows: ① A parts CAD drawing production reticle on a glass layer 10nm thick chromium plating film, according to the original definition of the light-transmissive and non-transmissive portion; ② wafer pretreatment by MASTER injection mold maker degreasing , polishing, pickling, washing purification methods of processing silicon surface to improve adhesion of the photoresist and the wafer; ③ aluminum evaporation, vapor deposition on a silicon wafer in a thickness of about 1μm aluminum film; ④ glue thrown in a silicon wafer uniformly coated with an aluminum layer of a positive photoresist film; covered ⑤ exposure, the wafer is coated with photoresist mask with a wavelength of ultraviolet light of 350 m through the photoresist mask selective irradiation; ⑥ development, the wafer was immersed in the developer after exposure, the photoresist was dissolved by the developer MASTER custom injection moulding and irradiated portions except
To get the same mask pattern; ⑦ to glue; ⑧ ICP etching, performed by plasma etching deep grooves; ⑨ to aluminum, the aluminum corrosion removal of the protective film, and ultimately obtained a partial structure micro-cavity inserts.

MASTER reaction injection moulding was first in the spring and Autumn period

Plaster mould was first in the spring and Autumn period, the ancestors with clay or stone carving out as a tool to coin money. Development up to now,the materials and processes are better than in MASTER injection molding supplies the past many advanced, in the material aspect, such as metal, resin, rubber, wood, plaster, several materials only gypsum is relatively easy to processing, no need of professional equipment, only need a knife or pieces of paper or wood, plus some soapy water as isolating agent can. Before making the plaster mold, people need to understand the properties of gypsum, gypsum powder is composed of a gypsum mine in quartz roasting by ground support, building materials stores a lot of big city in general can buy, their processing needs of small town of a class of area, is also the gypsum by grinding pestle, then roasted in a pot, burning fire, when the temperature to 800 degrees can be, but of course the quality no outside sell well. Nature when it comes to gypsum MASTER plastic container moldingpowder, chemically it is called semi  hydrated gypsum and burnt gypsum, it is mixed with water into a paste will soon after solidification, it is based on it by the flow of liquid into plasticity solid production molds and fire works, in the reaction process also generates heat. It should be noted, if too much moisture, will cause the solidified fastness variation condition, if need solid strength, should put the gypsum powder. Due to the condensation of solid gypsum can not be reused, so in the firing process must be fast, and be ready ahead of time and dosage of gypsum. Gypsum and gypsum products all have in common is absorbent, so people invented the slip casting method to make the blank, which is the removal of making plaster mold, another major use of gypsum.

Meter box enclosure design

The above advantages of the new cable branch box are derived from fiber reinforced polyester material itself. Also in the box design also gives this new branch cable boxes Unlike many metal boxwheel covers molding features: 1, with ventilation components for tank ventilation to prevent excessive distilled water Between the cabinet door, the upper and lower back, roof, doors and the rear plate have a vent assembly, the heat generated by the electrical components may be made ??of the space cabinets dehumidification process, can prevent metal cabinets pieces of rust, but also prevents the leakage current occurs. 2, isolated soil moisture Cable branch reaction injection mouldingbox with the base, by filling in the base and the base buried in the sand a certain depth below the surface, so that the soil moisture does not rise into the cabinets. 3, modular design makes installation easy Modular design not only makes easy to install, and very easy to replace the cabinet parts, simplifying spare custody.

Meter box box material

This composite material consists of two components: a substrate - a polyester-based resin; reinforcing material (abbreviated PC, SMC), which is so called transparent PC material, fiber Water purifier molding reinforced polyester material. PC transparent material, fiber-reinforced unsaturated polyester is an unsaturated polyester resin matrix composite material. Such insoluble both materials, flame retardant recyclable characteristics, the latter does not melt the material having the drawbacks thin wall injection moldingof non-recyclable three-dimensional structure of the physical network structure, four materials modified by the functional filler and reinforcing fibers have special become a high-performance engineering materials.
In Europe and other developed countries decades ago this material was widely used in the electrical field.
