Can acrylic materials be molded by injection molding

Acrylic. The material can be molded by injection molding.

The process of dissolving acrylic raw materials and pouring them into the mold is called acrylic injection molding. Goodbang.

Logos are generally made of acrylic panel blister to make car logos, and the injection acrylic process is less used, because injection molding is generally small scraps.

Injection molding: Injection molding uses pellets made by suspension polymerization, and the molding is carried out on ordinary plunger or screw injection molding machines. Table 1 is polymethyl methacrylate.

Typical process conditions for injection molding.

Note: Injection molded products also need post-treatment to eliminate internal stress, and the treatment is carried out in the 70-80 hot air circulation drying oven, and the processing time depends on the thickness of the product, generally about 4h.

Advantages: Acrylic is the best new material to be able to make sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic has the following advantages in addition to its unparalleled high brightness:

Good toughness, not easy to break; Strong restorativeness, as long as you dip the toothpaste with soft foam, you can wipe the sanitary ware new; The texture is soft, and there is no cold and biting feeling in winter; The colors are bright and can meet the personality pursuit of different tastes. Use acrylic to make basins, bathtubs, toilets.

Not only is it beautiful and durable, but it is also environmentally friendly, and its radiation is almost the same as that of the human body's own bones. Acrylic sanitary ware first appeared in the United States and has occupied the entire international market.

of more than 70%.

Disadvantages: Due to the difficulty and high cost of acrylic production, there are many low-quality and low-cost substitutes on the market. These substitutes, also known as "acrylic", are actually ordinary organic panels or composite panels (also known as sandwich panels).

Ordinary organic board is made of ordinary plexiglass pyrolytic material and pigment, with low surface hardness, easy to fade, and poor polishing effect after grinding with fine sand. The composite board has only a thin layer of acrylic on the surface, and ABS plastic in the middle.

It is easy to delaminate due to the influence of thermal expansion and cold contraction during use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.

Acrylic material is a kind of plastic material, the characteristics are high transparency, scratch resistance, easy to mold, acrylic material can be molded by injection molding, basically acrylic products are produced by injection molding.

Acrylic molds and injection molds are not the same type of molds and cannot be used universally.

Acrylic molds are mainly used in the production of acrylic products, such as billboards, display stands, light boxes, etc. This kind of mold is generally made of transparent or translucent plexiglass plate material, and is processed by cutting, bending, drilling and other processes.

An injection mold is a type of mold specially designed for injection molding. It consists of two parts, upper and lower, and the internal cavity is the same shape as the desired product. In the production process, the melted raw material (such as polypropylene) is sprayed into the injection molding machine, filled into the injection mold under high pressure, cooled and solidified, and then taken out to obtain the desired product.

Therefore, due to the different structures and functions of the two pairs, the cautious sales companion cannot be universal.

Summary. Dear, I'm glad to answer for you: Does injection acrylic need to be cooled A: Hello, dear! <>

needs to be cooled. Cooling increases the hardness. The most important thing about acrylic is its transparency, in order to reflect its transparency, first of all, the baking material must be in place, the injection temperature must be accurate, the product will be brittle and yellow, and the final cooling link is also very important, but the appropriate increase in cooling time and cycle times, so that the finished product is highly transparent.

Acrylic is a kind of plastic, the chemical name of acrylic is also called polymethyl methacrylate, it is a kind of thermoplastic developed earlier, with transparency, stability and good weather resistance, etc., has a wide range of applications in the construction industry.

Acrylic sheet features

1. Good hardness.

The main advantage of acrylic panel is high hardness, and its hardness is one of the indicators to measure the quality of the plate. The hardness index of a good acrylic panel can reach about 89 degrees, and the acrylic plate has a particularly good adaptability, which can be used for a long time in the environment of sun and rain, and has good anti-aging performance.

2. Good transparency and strong light transmittance.

The transparency and light transmittance of acrylic sheet are very good, up to more than 92%, because it can ensure the transparency and pure whiteness of the sheet during the production process.

3. Easy maintenance and strong plasticity.

Acrylic sheet is very easy to clean, generally with a rag dipped in water or soapy water can be wiped dry, and the acrylic sheet is highly malleable and easy to process and shape.

4. Strong impact resistance and rich colors.

Compared with other plates, the acrylic panel has strong impact resistance, which is more than ten times that of ordinary glass, and the safety performance is very high and variety, which is suitable for the decoration of different spaces.

It is made of plastic, which is a kind of plasticity polymer plastic material developed very early, and has good transparency, stable chemical properties, and excellent weather resistance, and dyeing is cheap, it is very simple to process, and it is also very good to look at from the outer cavity hail, and is widely used in the construction industry.

1. Warpage and deformation The warping and deformation of acrylic injection molding products are more difficult problems. It should be mainly solved from the aspect of mold design, and the adjustment effect of molding conditions is very limited.

Air bubbles The reason for the bubbles produced in the injection molding process of acrylic injection molding products is often due to the large wall thickness of the product.
