Urethane Casting
A manufacturer integrating scientific research, design, production and sales
In view of the special and excellent properties of urethane polyurethane elastomers, polyurethane elastomer products are used in almost all industrial systems,it is compression molding. Polyurethane products serve many industrial sectors, such as petroleum, mining, metallurgy, engineering machinery, automobile manufacturing, and polysilicon production, nuclear industry projects, textile printing and dyeing packaging, agriculture and animal husbandry, metal processing, cement ceramics, grain terminals, logistics and warehousing automation, powder molding and grinding, etc.; due to different industries and working conditions, the use performance of polyurethane elastomer products The requirements are different, and we can tailor products for users according to the special characteristics of the user’s products.Urethane casting services,low volume, durable parts with high production-level quality.
WS has a complete system of design, development, production, inspection and testing and good after-sales service, which can create good economic benefits for users when they use the company’s high-quality products. Under the mainstream of the international development trend, our company is actively expanding overseas business. Based on the principle of “survive by quality, develop by credit”, we believe that we will create a broader prospect in the near future.
Urethane Casting Products Features
1. Adjustable hardness: It still has the elongation and resilience of rubber under high hardness. The hardness range of the polyurethane sheet is Shore A10-D80.
2. High strength: Under the same hardness of rubber, the elongation at break, tear strength and bearing capacity of polyurethane are much higher. At high hardness, its impact strength and flexural strength are much higher than those of plastics.
3. Good wear resistance: its wear resistance is generally in the range of 0.01-0.10(cm3)/1.61km, which is about 3-5 times that of rubber.
4. Oil resistance: Polyurethane board is a kind of strong polymer product, which has little affinity with mineral oil and is hardly corroded in fuel oil and mechanical oil.
5. Good oxygen and ozone resistance.
6. Excellent vibration absorption performance, can be used for vibration reduction and buffering. In the mold manufacturing industry, it can replace rubber and springs.
7. Has good low temperature performance.
8. Radiation resistance: Polyurethane has good resistance to high-energy rays, and still has satisfactory performance under the radiation dose of 10-10 Ge.
9. Has good machinability. (turning, milling, grinding and drilling are available)
Polyurethane material, short for polyurethane, is an emerging organic polymer material, known as the “fifth largest plastic”, and is widely used in many fields of the national economy because of its excellent performance. We have some knowledge about polyurethane elastomers. We are familiar with the production and application of polyurethane elastomer products. Please tell us your requirements for the use of polyurethane elastomer products. WS is willing to work with you to complete products that satisfy you.
Key points in the production of urethane products Casting
Polyurethane production, need to pay attention to the following key points:
1. Ensure the dryness of the polyurethane, otherwise it will affect the elasticity problem in the later stage. When the polyurethane is decomposed, it is necessary to dry it, which is a step that can maximize the effectiveness of the later elasticity. If the drying treatment is not carried out, the subsequent work will not be completed smoothly, and the resulting product will contain air bubbles.
2. When dissolving, the temperature is first high and then low, and the temperature cannot be kept constant. When dissolving, pay extra attention to the temperature. One set the temperature to a parabolic trend, and it cannot be in a constant temperature state all the time, otherwise the polyurethane will always be in a liquid state and cannot be stabilized into a solid state.
3. Use the low temperature of the water tank to set the polyurethane, and the water speed should be uniform and stable. There are certain conditions for polyurethane molding. Usually, the low temperature of the sink is used, and the water in it must be circulating water, and the water speed must be kept uniform, otherwise the molded polyurethane products will have defects.
How should urethane rubber products be cleaned?
Rubber products are a kind of products that are used in many industries. The following is a detailed introduction to how to clean polyurethane rubber products.
1. Chemical cleaning
Use professional mold washing water or dilute sulfuric acid to directly clean the scaled part, the speed is fast and effect is good, but it will produce a pungent smell and pollute the environment. This method has been gradually phased out, and some small processing plants are still using it.
2. Mechanical descaling
At present, most rubber product manufacturers are equipped with sandblasting machines, which can directly blast the surface of the mold with resin sand. This method has good cleaning effect and is a commonly used mold cleaning method.
3. Ultrasonic descaling
Shake off the dirt in the cavity by using the principle of frequency and wavelength. It is better to use with mold washing water, very good, but the cost is relatively high.
4. Mold electroplating
A layer of hard chrome is plated on the surface of the mold. Practice has shown that this method can effectively solve the problem of deposits attached to the surface of the mold. This method is more suitable for a large number of rubber product molds.
The above is the cleaning method of polyurethane rubber products organized by www.wsmcmold.com for you, hoping to bring some help to customers who read this article.
