Hand Lay-up &VIP Process Product

Hand Lay-up Process

The hand lay-up process is a process in which fiberglass fabrics and resins are alternately laminated on the mold by hand, and then solidified and formed into FRP products.

Due to its unique and irreplaceable characteristics, the hand lay-up process is still widely used as a main FRP forming process, and is suitable for FRP containers, FRP bodies, FRP pipes, FRP water tanks, furniture, corrosion-resistant FRP equipment, etc.

Advantage：

The requirements for equipment are not high, only simple molds and tools are needed, and the capital investment is small
The production technology is easy to master, and employees can start working after short-term training
The formed products are not restricted by shape and size.
It can be used in combination with other materials (metal, foam, wood) etc.
It can be constructed in use or outdoors

Vacuum Infusion Process (VIP)

The vacuum infusion process (VIP) is to lay the designed reinforced material preform in the mold cavity, use the vacuum system to draw out the air, form a negative pressure in the mold cavity, and use the pressure generated by the vacuum to pass the resin through the pre-laid The pipe is pressed into the fiber layer, and the resin completes the infiltration of the reinforcing material preform in the process of flowing and filling the mold, and solidifies and forms to obtain a composite material component.

Advantage：

Higher quality products: no excess resin is left, the glass fiber content is high, up to 70% or even higher, and the resulting products are lighter in weight and higher in strength.
Less resin loss and cost saving;
The resin is evenly distributed;
Less volatilization in the production process, protecting the physical and mental health of operators;
Using a single-sided mold: Only one side of the mold can be used to obtain smooth and flat products on both sides, which can better control the thickness of the product and save mold manufacturing costs and time.
