SMC
Sheet Molding Compounds，the sheet molding compound. The main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various additives.
One-time compression molding at high temperature
High mechanic strength
Material has a light specific gravity
High integration
Corrosion preventive
High insulation strength
Excellent flame retardant performance
Flexible product design
Polyurethane Prepreg
Polyurethane prepreg is a combination of two-component polyurethane resin impregnated with continuous fiber and its fabric under strictly controlled conditions. It is an intermediate for the manufacture of advanced composite materials.
Product process:
Cut the polyurethane prepreg according to the shape and size of the product, spread the shape of the product on the model, and place it on the mold for compression molding.
High accuracy of product dimensions
Has a certain degree of adhesion
Excellent effect and high quality
高集成性
Low one-time investment
Short molding cycle
Good secondary processing performance and weather resistance
Good mechanical properties
LFT
LongFiber Reinforced Thermoplastics-Direct
Cut glass fiber with the equipment and gently mix it into the molten polypropylene, and then directly put it into the mold for compression. We will also add different additives as required by customers so that the products can meet the performance requirement of customers.
Highly automotive
High production efficiency
Large fiber length
Rapid adjustment of formula ratio;
LWRT
Low-weight reinforced thermoplastics, a sheet made of glass fiber needled felt as a reinforcing material and polypropylene composite.
Product process:
1. Put the LWRT sheet in an electric oven, the temperature is controlled between 200-220℃, and the time is 50-70 seconds, and the LWRT sheet is heated and softened;
2. Stack the baked LWRT sheets in the mold, and then close the mold, the pressure is set at 0-200T, and the time is 20-40s.
Excellent sound absorption performance
Small investment in molds and presses
The upper and lower surface covering materials can be customized
For irregular products, the material utilization rate is very low
GMT
GMT：Glassfiber mat reinforced thermoplastics，It is a kind of sheet compounded with modified polypropylene and glass fiber needle taken as the reinforcement material.
1. Preheat the cut sheet (3-8min). The internal temperature is required to be greater than 190°C and the surface temperature is not greater than 240°C. The preheating can be done by infrared ray or air convection.
2. The preheated sheet is put into the mold cavity within 15s in a temperature range of 40~60℃, then compound the mold immediately. The molding pressure is 15-25MPa, and the molding cycle is 1~2min.
Free design
High impact resistance
Recyclable.
High strength and high rigidity
