The emergence of Yoogi means the growth of my country's chemical industry. This product can be processed by CNC, or it can be carved and decorated by hand. It will not have wood grain like trees and will not fluff when carved. It can engrave very fine patterns (such as wooden molds for shoe sole molds), and if it is machined, it will be smooth even without sanding.

Yokoki was originally produced in my country using unsaturated resins, that is, glass beads are added to the unsaturated resin, and then a curing agent is added to extract the air inside to solidify it to produce a product called Yokoki. Unsaturated resin products can be made in many specifications, such as 700*450*thickness (20-250), 1500*500*thickness (30-250), 1500*400*thickness (30-250), etc.

With the continuous development of industry (automobiles, ships, toys, home appliances, etc.), substitute wood made of unsaturated resin cannot meet the needs of customers with high quality requirements (unsaturated resin is not resistant to high temperature, easy to deform, strong odor, etc.) , The production process of epoxy resin is similar to that of unsaturated resin, but the production process of polyurethane is quite different, the required environment is different, the mechanical equipment is also increased a lot, and the production is much more difficult. Because the properties of the raw materials are different, the substitute wood produced from polyurethane materials and epoxy resin materials has very good physical properties such as toughness, hardness, dimensional stability, temperature resistance, compressive strength, and bending strength.

Polyurethane resin inspection tool substitute wood materials are relatively better than epoxy resin substitute wood materials: better toughness, higher stability, more environmentally friendly, and more suitable for inspection tools, fixtures, fixtures, etc., with higher precision The product. The quality of polyurethane substitute wood is relatively stable, the toughness is quite good, and there will be no deformation, while the substitute wood made of epoxy resin may deform when the material is relatively thin; like some other small factories in China The quality and performance of the made wood substitutes are still quite serious (too fragile). The main reason for this is that they are inaccurate in selecting materials and inferior in workmanship. In our country, we have learned that most of them are some simple mixing processes such as epoxy resin and curing agent. Moreover, there is no actual technical content, no quality certification such as ISO, and no professional staff to perform inspection tools on behalf of wood. In-depth research is all simple manual operations, some do not even know about the inspection tools, and do not understand the performance of the raw materials, so they have made the inspection materials, just relying on wild boasting. The more well-known inspection tool manufacturers and OEMs generally do not use these domestic epoxy resin substitute wood products at all. Only those small companies that don’t know much about the selection and standards of inspection tools (or some less demanding inspection tools) will use some poor materials, search on the Internet, people brag about it, and don’t know the other company at all. The technical strength of the company and product safety guarantee, as long as the price is cheap.

Because the threshold for domestic Yogi production is low, the investment amount does not need to be very large, and its staff are not many, so many people come out from Yogi Factory for a few months and find a few wealthy friends to produce Yogi. , Or sell the formula to another company. Very few of our country’s better substitute wood inspection tool material manufacturers can have the development capabilities of this product, and most of the resin substitute wood manufacturers cannot produce polyurethane in 2013. Products; therefore, most of the epoxy resin substitute wood appearing on the market are "counterfeit" versions (produced by buying and selling other recipes, without substantive technology), and even some manufacturers with bad credit use unsaturated resin substitute wood as epoxy Resin substitute wood sales to deceive users.

In foreign countries, such companies as Huntsman also produce many low-density substitute wood, such as 0.08, 0.24, 0.32, and 0.47. These grades of substitute wood products have R&D capabilities in some Chinese manufacturers in 2013. There is still a certain degree of difficulty, and it may take some time and effort.
