Composite PV Frame Pultrusion Mold

Product: Glass fiber Reinforced Composite PV Frame Pultrusion Mold

Site: Customer’s composite solar frame production workshop

Target Market: Global PV module manufacturers & overseas solar power projects

Project Overview

We are a professional mold manufacturer focusing on pultrusion molds for composite profiles. This case presents the stable mass production performance of our custom built composite photovoltaic frame pultrusion mold running at the customer’s workshop.

Composite PV frames are a preferred solution for overseas solar projects thanks to their insulation performance, lightweight property and excellent salt spray resistance. Nevertheless, high glass fiber filled materials bring technical challenges: heavy abrasive wear, difficult material flow, profile warping and poor wall thickness control.

Targeted at the characteristics of glass fiber composites, we have specially optimized the mold runner and calibration structure. After on site commissioning, the mold was put into continuous pultrusion mass production. The finished frames are supplied for export photovoltaic modules.

On-Site Mass Production

The customer operates an automated composite pultrusion production line. Our mold can run continuously for long periods without frequent shutdowns for mold repair, perfectly matching the production rhythm of customers’ high volume foreign trade orders.

Benefiting from the well balanced runner design, composite materials achieve even feeding. The pultruded profiles feature full cross section, uniform wall thickness and excellent straightness. Common defects of composite profiles such as distortion, warpage, surface blemishes and out of tolerance dimensions are effectively eliminated.

Pultruded frames are well adapted to subsequent cutting, punching and assembly processes with stable good product rate. Capable of 24 hour non stop production, the mold boosts customer output, reduces waste and downtime losses, and fully satisfies strict inspection requirements of overseas photovoltaic industry.

Core Advantages of Our Mold

• Custom built for glass fiber reinforced composites Optimized runner and pressure balance structure solve unstable feeding and uneven fiber distribution, guaranteeing consistent forming quality of composite PV frame profiles.
• High wear resistance for extended mold service life Key forming zones of the mold adopt wear resistance strengthening treatment to withstand continuous scouring from glass fibers. It extends mold service life, lowers customer costs for mold repair and replacement, and fits long term high volume export orders.
• High forming precision complying with international PV standards Precision calibration tooling delivers tight dimensional tolerance and good profile straightness. Finished frames can pass international salt spray tests, weathering tests and visual inspections, suitable for global markets including Europe, America, Southeast Asia and the Middle East.
• Easy commissioning and reliable mass production performance Simple on site setup and fast trial production. High yield rate cuts material waste and production halt time. It helps customers shorten delivery lead time and enhance competitiveness in the global photovoltaic market.
