Sponge baby crab owner Fiberglass sculpture is made of Fiberglass, commonly known as Fiberglass. Reinforcement plastics based on unsaturated polyester resin.

It is widely used in the market because of its low price, good workmanship and good comprehensive performance after curing. It can not only be used as decorative arts but also as high-end products such as flower pots, sculptures, furniture and so on.

The detailed process of Fiberglass sculpture for sponge baby crab owner: die dressing – release agent – coating resin – cutting glass fabric – gelatinization – room temperature curing – release – hair removal by cutting line – edge sealing – ripening – spraying paint.

Mold dressing: Clean the mold and wipe it with soft gauze. No impurities can be left on the surface.

Glass Fiber Reinforced Plastic Manufacturing Paint Releasing Agent: Paint Releasing Agent must be uniform without omission. Polyvinyl alcohol needs to be fully dried. Removal agents such as polishing wax and non-silicon oil paste need to be parked for two hours to volatilize the solvent.

Coating resin: Coating ingredients should be fully mixed, especially when fillers and pigments are used. Non-uniform mixing will cause spots or stripes on the surface of products, which will affect the appearance. The thickness of the rubber coat should be precisely controlled. During construction, the brush can be used. The gel coat solidifies to the finger contact and feels slightly sticky but does not stain the finger, then it can be laminated.

Cutting glass fabrics: According to the size and thickness of the parts, the number of layers of glass fabrics needed is calculated. Glass fabrics should be slightly larger in size than molded tires. Sample blanking may be used if necessary.

Glass Fiber Reinforced Plastic Manufacturing Adhesive: According to the required gelling time and environmental conditions, the type and proportion of curing agent and accelerator are selected. When color products need to be made, a small amount of color paste can be added.

Paste: First brush a thick layer of resin as evenly as possible on the rubber coat, then lay the first layer of glass reinforcement material, preferably surface felt or 0.16mm glass cloth, and press with a brush, so that the resin can easily penetrate along the glass fabric. Don’t pour resin on glass fabric immediately before it is completely soaked. Continue pasting the resin and glass fabric below with the above method until the required thickness is reached. For each layer of paste, the glass fabric should be completely soaked. Make each layer of fabric exhaust bubbles and good tire attachment. After many tests, it is suggested to use a layer of surface mat, a layer of chopped meat, and then paste the glass cloth until the thickness of the structure, so as to avoid the fiber pattern penetrating the rubber coating, affecting the surface quality of the products. When embedding metal parts, the thickness of the products should start at the place where the inserts are embedded, and the transition is slow and thin. When reinforcing ribs need to be added, it is better to put them directly before the last layer of glass fabric is laid. The core should be covered with glass fabric impregnated with resin, and then the last layer of glass fabric should be spread over the whole area of the product.

Room temperature curing: After pasting, the parts should stay on the mold for more than 24 hours to complete the curing period.

Fiberglass manufacturing demolding: first remove the edge of the part, and then remove the part. Compressed air can be blown between the die and the parts that are difficult to produce. To support the edge and repair the defect according to the cutting line: Cut the edge along the edge line of the part with a curve saw or angle grinder, and repair the defect on the surface of the part.

Fiberglass Manufacturing Edge Sealing: Fiberglass is not water-resistant. The cut section of Fiberglass products is easy to be stratified after immersion due to fiber exposure, which affects the quality of products. Therefore, the Fiberglass parts should be sealed. The method is to use resin glue with curing agent and accelerator to uniformly coat a thin layer of glue on the cutting section of parts.

Fiberglass manufacturing ripening: After demoulding, the parts must be stored for more than a week to ensure complete solidification of the parts.

Fiberglass Manufacturing Spray Paint: Before spraying, all the remnants of the film-removing agent on Fiberglass products should be washed out. Paint according to the color of the product. Low-temperature paint should be used. The drying temperature of the paint should not exceed 80 C.
