High quality glossy gel coat finish fiberglass cover factory

We are a factory, Customize design available, OEM/ODM welcome ! 

Our diversified product scope

Fiberglass hand lay process

is the first production process which our factory had. Established in 2000 year, our first fiberglass product was made via hand lay up process.

Hand lay up is an open molding process, it is the most common and least expensive open-molding method because it requires the least amount of equipment.
Fiber glass matting are placed by hand in the mold and resin is applied with a brush or roller.
It is the best choice for the fiberglass products with glossy gel coat finish, large complicated shape and low volume.
The most important factor for hand lay process producion is the skill of workers, after development with over 20 years, our workers are very stable and experienced, 80% of our workers have been worked in our factory with more than ten years.
We had strict working instruction for every raw material and every step during the whole production.
We are very proud with glossy gel coat finish of our fiberglass parts.

Advantanges:
1) Ideal for all shapes and sizes
2) Low mould investment.
3) Suitable for low volume parts.

Our Production capacity:
1)Complete production lines.
2)More than 50 skilled workers for fiberglass hand lay process.
3)Experienced for manufacturing fiberglass hand lay up products from different field.

RTM

called resin transfer molding, it is vacuum assisted, closed molding process. Male mold plus female mold structure achieves two smooth surfaces, which is the major advantange of this process.
Fiberglass reinforcement mat or woven roving is placed in the mold, then closed and clamped molds. Catalyzed, low-viscosity resin is pumped into mold cavity under pressure, until the mold is filled.
Once the resin is cured, the male mold is removed and the part is de-molded from the female mold.
Suitable for medium volume and high surface quality parts, RTM ( resin transfer molding ) is usually considered an intermediate process between the hand lay process with low mold investment and fiberglass sheet molding with higher mold investment,

Advantanges:
1) High glossy gel coat finish.
2) Both smooth sufaces.
3) Suitable for mid volume products.
4) High streigth-to-weight requirements.
5) Dimention stability bether than fiberglass hand lay up parts.
6) Labor saving, higher efficiency than fiberglass hand lay parts.

Our Production capacity:
1) Complete three production lines.
2) Experienced workers, engineers and QC.

Fiberglass compression molding

includes SMC (Sheet Molding Compound ) and BMC (Bulk Molding Compound).

The difference between SMC and BMC is the length of glass only.Different length of glass results in different mechanical character.

Sheet Molding Compound (SMC) is a compression molding compound often used for larger parts where higher mechanical strength is needed. SMC is a fiber reinforced thermoset material.
Glass reinforcement is between 10% and 60%, and glass length is slightly longer than Bulk Molding Compound (BMC) - between 1/2-inch and 1-inch (25mm).

Sheet molding compounds can be molded into complex shapes.
Superior mechanical properties and surface appearance, plus excellent electrical insulation make this thermoset material ideal for automotive Class A body panels,
high-strength electrical parts, business equipment cabinets, personal watercraft, and various structural components.

Bulk Molding Compound (BMC) is a thermoset plastic resin blend of various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous.
Bulk Molding Compound (BMC) is highly filled and reinforced with short fibers. Glass reinforcement represents between 10% and 30%, with glass length typically between 1/32-inch and 1/2-inch (12.5mm).
Depending on the end-use application, bulk molding compounds are formulated to achieve close dimensional control, flame and track resistance, electrical insulation, corrosion and stain resistance,
superior mechanical properties, low shrink, and color stability. Its excellent flow characteristics, dielectric properties, and flame resistance make this thermoset material well-suited to a wide variety of applications
requiring precision in detail and dimensions as well as high performance.

Advantanges:
1) Good finish on both sides.
2) High dimension accuracy.
3) Fast cycle times.
4) Uniform fiberglass products'quality.
5) Less labor ratio.

Our Production capacity:
1)Complete production lines, 11 hydraulic compression machines.
2)Pressure of hydraulic compression machines from 315tons to 3000tons.
3)Two shifts production.
4)The maximum products with 6.2meters length.
