1.FRP Pultrusion:
Pultrusion is a continuous process for the manufacture of products having a constant cross section, such as rod stock, structural shapes, beams, channels, pipe, tubing, fishing rods, and golf club shafts. Pultrusion produces profiles with extremely high fiber loading, thus pultruded products have high structural properties.
Pultrusion is a manufacturing process for producing continuous lengths of FRP structural shapes. Raw materials include a liquid resin mixture (containing resin, fillers and specialized additives) and reinforcing fibers. The process involves pulling these raw materials (rather than pushing as is the case in extrusion) through a heated steel forming die using a continuous pulling device. The reinforcement materials are in continuous forms such as rolls of fiberglass mat or doffs of fiberglass roving. As the reinforcements are saturated with the resin mixture ("wet-out") in the resin impregnator and pulled through the die, the gelation (or hardening) of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.
FRP Epoxy Insulation Dogbone and Corner piece for transformer are the composite material with unique characteristics, which is produced by the process of drawing and extruding without alkali glass fiber impregnated thermosetting resin. Most rods are composed of polyester resin and fiberglass. These composites can be formed into practically any shape by using the pultrusion process, it has the advantages of high mechanical strength, excellent electrical properties, flame retardant, corrosion resistance, arc resistance, dimensional stability, long life cycle etc.

FAQ
Q1: How about MOQ?
MOQ is according to different products. Whatever you need, we are glad to quote best price with good quality.
Q2: Can you send samples for testing?
Samples are free supplied, but express freight should be taken by client. After making order, we'd like to return freight back.
Q3: How can you guarantee the quality of mass goods is same as the sample sent to me before?
We kept another same sample and marked on company when we sent to customer. So our production will be based on.
Q4: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.
Q5: When customer respond quality issues after pick up goods, how to deal with?
1) Customer could supply photos of issued goods for our sales staff and then we'll verify which part is wrong.
2) If the issue is confirmed, company will negotiate with customers and compensate in coming orders.
