Fiberglass Pultrusion Machine

Plastic deformation such as cavity collapse, hole enlargement, corner inversion and upsetting and longitudinal bending of the punch. Special hot work equipment makes the surface temperature of the mold cavity higher than the tempering temperature of the hot work equipment steel, and the inner wall of the groove is crushed or piled due to softening.

Wear loss: Wear loss refers to blunting of the blade, rounding of edges and corners, plane subsidence, surface grooves, peeling mucous membrane, etc.
Wear failure: Wear cracks originate in areas with greater stress, especially stress concentration areas. When fatigue cracks, the broken door is divided into two parts. One part is the fractured section at the fatigue point caused by the growth of fatigue cracks, which appears in the shape of a shell. The source of fatigue is located in the shell. pole. The other part cracked suddenly, resulting in an unyielding and rough section.
Cracking failure. Common phenomena of cracking failure include: chipping, teething, splitting, breaking, expansion cracking, etc. There are two cracking processes of FRP pultrusion equipment, one-time cracking and fatigue cracking. One-time cracking means that the equipment occasionally cracks suddenly during stamping, while fatigue cracking cracks will expand after they are initiated.

FRP pultrusion process

Glassfiber Pultruded Machine

The pultrusion process was studied as early as 1948. It was first registered and patented in the United States in 1951. It was only in the early 1970s that it truly entered the field of structural materials. After that, the pultrusion process became a widely used process technology and gradually attracted the attention of all sectors of society. With the improvement of raw materials and equipment manufacturing levels, many key technologies of the pultrusion process have made major breakthroughs and achieved rapid development.
