BMC Resin Manhole Cover Molding Process Features

{dede:global.cfg_gsname/} | Updated: 2019-12-16 08:00:04
BMC resin manhole cover is made by mixing agglomerated short glass fiber, unsaturated resin, filler and various additives. Reinforced. Features: Its characteristics are strong corrosion resistance and weather resistance.
The compression molding principle and process of BMC molding compound is basically the same as other thermosetting plastics. During pressing, a certain amount of BMC agglomerate molding compound is put into a preheated compression mold, and then pressurized and heat-cured to form the desired product.
 BMC compression molding process features:
1. The amount of wasted material is small, usually only 2% -5% of the total material used. The actual amount of material loss also depends on the shape, size and complexity of the molded product.
2. In the molding process, although the BMC molding compound contains a large amount of glass fibers, it does not produce a strong orientation of the fibers, so the product has higher uniformity and denseness, and the residual internal stress is also smaller.
3. During processing, fillers and fibers rarely break, so high mechanical and electrical properties can be maintained.
What are the advantages of BMC resin manhole covers:
1. The resin manhole cover has a very long service life and is durable and does not cause internal damage. The resin manhole cover uses high-performance resin, glass fiber and a special production process formula, thereby ensuring the penetration of the resin in the glass fiber and greatly enhancing the two. Adhesive force makes the material load
Under the action of load, no internal damage occurs, thereby ensuring the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
3. Resin manhole cover has strong anti-theft performance: Aiming at the widespread theft of manhole covers in the society, it has caused many adverse social impact problems. Our company produced a new type of manhole cover-resin manhole cover. This resin composite manhole cover uses unsaturated resin, glass fiber and other materials and
The reinforcing steel skeleton is compounded by a special production process, and is formed by high-temperature grinding and pressing once. The material has no recycling value. It is very difficult to remove the reinforcing steel (the cost of removing the reinforcing steel exceeds the value of the reinforcing steel). Therefore, it has the function of active anti-theft.
