DownloadLow-shrinkage
SMC has minimal shrinkage upon curing, resulting in reduced distortion and improved accuracy.
Product Categories
Union SMC6005 with A class surface and low linear shrinkage with 0.02, fiberglass content around 33% to win the good mechnical properties, suitable for automotive application like inner panels Structural parts, and A class requirement like hoods, roofs and some other auto parts, other high flexture strength composites as well.
1. Sheet molding compound 6005 based on iso-phthalic polyester resin with RAL9002 white color, other RAL list color available, chopped strand 25.4mm in length to reinforce materials, with good weather resistance, good water resistance, mostly application is auto parts. smc can achieve a weight reduction of 28% to 45% in applications such as car fenders, hoods, rear doors, and battery boxes. The specific strength of SMC is close to magnesium alloy, but the cost is much lower than magnesium alloy,The molding process is simple, and the mold cost and maintenance cost are low. smc also have good corrosion resistance, vibration absorption, and noise reduction properties, making them one of the best materials for lightweight vehicles.
2. Pressing temperature: upper mold (bright side of product)/lower mold: 149-152℃/140-143℃.
3. Molding pressure: Calculated based on the projected area of the product, the recommended pressure per square meter is 800T-1000T.
The density of Class A surface fiberglass composite material(SMC) is only 1/6 of steel, but its elastic modulus and strength are 3 to 4 times that of plastic. It not only has good dent resistance, strength and anti-corrosion properties, but also has high Surface quality, the appearance after painting can be perfectly consistent with the metal appearance.
As countries around the world improve vehicle fuel efficiency and emission standards, the development and application of lightweight technology in the automotive industry is imperative. Relevant research from the China Automotive Research Center shows that reducing the weight of the vehicle by 10%, can increase fuel efficiency by 6% to 8% and reduce emissions by 4%. That is, for every 100kg reduction in vehicle weight, emissions can be reduced by 6% to 7%. Fuel consumption. Among various lightweight materials, sheet moulding compound has become a hot topic in the development of automobile lightweight due to their superior properties such as low density, high strength, corrosion resistance, dent resistance and flexible design freedom.
SMC has minimal shrinkage upon curing, resulting in reduced distortion and improved accuracy.
SMC material possesses excellent strength properties, providing structural integrity and load-bearing capabilities.
Gloss value represents a mirror reflection ability of the surface of the object to the light, the greater the value, the stronger the reflection ability of the light, the brighter the surface of the object seen by our human eyes, and the reflective object can be seen through the surface of the object.
Coloring refers to the application of color to SMC finished products, which embellishes or adds highlights to the appearance, making it more vivid, interesting or attractive.

Union Composites
Union focuses on the manufacturing of composite materials and is the designated distributor of Jushi Group, which can provide customers with composite products of stable quality. Union is committed to meeting diverse customer needs and can customize products.
Q: Can you make the same color of our SMC product?A: Yes. We can customize as your requirement. For color, we use the lastest version of RAL color code.
Rugular color example:
RAL7035 Light Grey
RAL1015 Light Ivory
RAL 9004 Signal Black
If you have strict standard for the color, you can send a small sample piece, then we can compare and provide to you.
How can u make sure the different batches of your product have the same color Our QC dept. have spectrocolorimeter to make sure the final product of different batches product have a ΔE<2.
Q: What is the shelf life of SMC?A: Usually you can keep 5~6 months from production to use, if in the suitable storage condition. Please store it in and keep in a cool, ventilated and dry place below 25°C. Avoid fire, keep away from heat and radiation sources. Avoid water and prohibit exposure to sunlight and open storage.For foreign customers, we will use Reefer container (18C temperature). Once you open the package, please use it all during three days.
Q: How do you pack the SMC?A: We use zig-zag way to load into the pallet. Pallet size: 1.06*1.06*0.7meters, 1000kg per pallet. (±5% difference)In 20ft Reefer container, load 20000kg (20tons)， 20pallets. The materials are sealed with multi-layer PP film packaging, plus aluminium-plated film to prevent the Light Source. The outer layer is packed in multi-layer cartons and fumigation-free pallets.
Q: Can we get samples?A: Yes. We can provide free sample. (within 10kg)
Q: What is the delivery time?A: Usually 7days from other to delivery.
