SMC molded gas meter box a sheet-like mold material mixed with more than a dozen composite materials such as unsaturated polyester resin, glass fiber, low shrinkage, calcium powder, and various additives, and formed by forging press at high temperature and high pressure. It has excellent advantages such as corrosion resistance, insulation, flame retardant, light weight, beautiful appearance, inability to recycle, and long service life (outdoor design service life can reach more than 40 years, indoor design service life can reach more than 60 years.
SMC gas meter box production process
1. Preparation of raw materials:
SMC sheet: Select Sheet Molding Compound that meets the requirements of gas meter boxes, and must have corrosion resistance, aging resistance, flame retardant and other characteristics.
Other materials: such as sealant strips and metal parts, which are easy to install and maintain. (hinges, locks, etc.).
2. mold preparation
Mold design: Design the mold according to the size and functional requirements of the gas meter box to ensure that the box structure is reasonable and easy to install and maintain.
Mold preheating: Heat the mold to a suitable temperature (usually 140°℃-160°℃) to ensure adequate flow and solidification of the SMC material
3. compression molding
Cutting SMC sheet: Cut SMC sheet according to mold size.
Charging: Place the cut SMC sheet into a preheated mold.
Hot pressing forming: The SMC sheet is formed in a mold at high temperature (140℃-160 ℃) and high pressure (10-20MPa). The curing time is from a few minutes to ten minutes, and the specific time depends on the thickness and size of the box.
4. cooling and demoulding
Cooling: The molded box is cooled in the mold to a suitable temperature (usually below 60℃).
Demoulding: Remove the formed gas meter box from the mold.
5. post-processing
Trim: Remove excessive parts such as burrs and burrs.
Drilling: Drilling holes are drilled on the box body according to design requirements for installing watches, pipes and accessories.
Surface treatment: Polishing, painting or other surface treatment to improve appearance quality and weather resistance.
6. Assembly
Installation accessories: Install hinges, locks, sealing strips and other accessories.
Installation of functional components: Install gas meter brackets, pipe interfaces, etc. as required.
7. quality inspection
Appearance inspection: Check whether the surface of the box is smooth, free from cracks, bubbles and other defects.
size inspection: Ensure that the box size meets the design requirements.
Flame retardant test: Test the flame retardant performance of the box to ensure that it meets the safety standards of the gas meter box.
Airtightness test: Test the sealing performance of the box to ensure that it is waterproof and dustproof.
8. packaging and warehousing
Packaging: Use shockproof and moisture-proof materials to package the gas meter box. Warehousing: Put finished products into warehouse and wait for delivery.

Our company uses a new composite material SMC to produce gas meter and flowmeter boxes. The box produced by this material is beautiful and generous, and is currently widely used. It has been in use for nearly ten years. The newly developed SMC molded gas meter box is a sheet-like mold material mixed with more than a dozen composite materials such as unsaturated polyester resin, glass fiber, low shrinkage, calcium powder, and various additives, and formed by a forging machine at high temperature and high pressure. It has the advantages of excellent corrosion resistance, insulation, flame retardant, light weight, beautiful appearance, inability to recycle, and long service life (outdoor design service life can reach more than 40 years, indoor design service life can reach more than 60 years).
The meter box has better physical, chemical properties and mechanical strength than gas meter boxes such as plastic, metal, and hand-laid FRP. It has the functional effects of being more convenient to install and use, and more thoughtful and strict user management. The surface of the box is printed with color separation screen with good visual effects, and it also has advertising functions to beautify the community environment, warn safety, and highlight customers 'beautiful corporate image. This meter box is widely used in centralized gas management systems in urban residential areas and high-low-rise buildings. It is safe and beautiful to use.
