About Polygram
Leveraging its deep technological accumulation and outstanding innovation capabilities, the company has broken through the traditional industry bottlenecks of high cost and low efficiency in carbon fiber molding, providing customers with a one-stop service covering the entire process from material design, raw material production, mold development to injection molding.
The company provides targeted, lightweight, high-strength, and corrosion-resistant cutting-edge product solutions for high-end industries such as aerospace, military, new energy vehicles, low-altitude economy, robotics, semiconductors, and sporting goods, and has gradually developed into a well-known enterprise in the industry.
We are a high-tech enterprise specialized in the R&D and manufacturing of thermoplastic (LFT) carbon fiber composites, conductive and anti-static materials, and graphene thermal conductive materials. We are committed to providing
customers with one-stop full-process services ranging from material design, raw material production, mold development
to injection molding.Relying on our profound expertise in polymer modified materials, precision mold manufacturing and
composite material processes, we have broken through the traditional industry bottlenecks of high cost and low efficiency
associated with carbon fiber. We deliver high-performance product solutions featuring lightweight, high strength and
corrosion resistance for high-end industries such as aerospace, military industry, new energy vehicles, low-altitude
economy, robotics, semiconductors and sports equipment.
LFT long fiber reinforced thermoplastic engineering materials, comparedto ordinary short fiber reinforced thermoplastic materials (fiber length isless than 12 mm), the LFT process produces thermop
lastic engineeringmaterial's fibers in lengths of 5-25 mm. The long fibers are impregnatedwith the resin through a special mold system to obtain long strips that
are fully impregnated with the resin, and then cut to the length asrequired.The most used base resin is Pp, followed by PA6, PA66, PPAPA12,MXD6, PBT, PET, TPU, PPS, LCP PEEK. etc。
Conventional fibersinclude glass fiber, carbon fiber, special fibers include basalt fiber andquartz fiber, etc. Depending on the end use, the finished products canbe used for injection molding, extrusio
n, molding, etc. or directly usedfor plastic instead of steel and thermoset products.
