Why Manufacturers & Procurement Leaders Choose Jinxin

Factory-Accepted Before Shipping

We don’t just check mechanical movement—we run full-load production trials before shipment.

  • Dimensional Verification: We run the line to prove the mold delivers your exact pipe dimensions and tolerances. For optical-grade profiles, we verify surface clarity and absence of die lines under production conditions.
  • The “Start-Up Recipe”: We record the successful processing parameters (temperatures, speeds) used during the trial. You receive this Data Sheet to skip the guesswork and start production immediately.
  • Material Calibration: Using special material? We recommend shipping your raw material to us for testing. We calibrate the machine to your reality, ensuring precision from start.

  • Our LED cover profiles ship to distributors across the Middle East, and any surface scratch means a rejected shipment. We asked Jinxin to add an inline film applicator to protect the profiles immediately after cutting.

    They integrated the unit into our line — now every piece comes off with PE film applied automatically. No manual handling, no scratches.

Frequently Asked Questions About PC Profile Extrusion

For clear or high-gloss PC profiles, the die flow surface and finish directly influence drag marks, die lines, and flow/vibration lines.

Using an S-136H mirror steel die with mirror polishing helps reduce these appearance defects, while final results still depend on resin grade, drying condition, and a validated temperature/shear window.

Dimensional stability relies on steady vacuum sizing, uniform cooling, and mechanical support. The sizing table uses a 3 kW vacuum pump regulated by a 4 kW ABB inverter, with vacuum pressure controllable via HMI or manual mode.

For wider profiles, an optional support frame helps reduce sagging in the water tank, supporting more consistent sizing during continuous production

Yes. Polycarbonate is highly hygroscopic and must be thoroughly dried before processing. Industry guidelines recommend pre-drying at 100–120°C for 2–4 hours to reduce moisture content below 0.02% for optical-grade profiles.

Residual moisture in the melt causes hydrolytic degradation, leading to bubbles, splay marks, and loss of optical clarity in the finished profile. While the dehumidifying dryer is not part of our standard extrusion line scope, we provide the full drying specification with every order and can source one as part of a turnkey package.

Yellowing in PC profiles is primarily caused by thermal degradation — when barrel temperatures are set too high, residence time is too long, or the resin retains excess moisture.

Polycarbonate has good thermal stability below 300°C but begins to decompose above 340°C. Black spots typically form when molten material stagnates in dead zones inside the barrel or die and carbonizes over time.

Our line addresses both issues: the screw geometry is designed specifically for amorphous, high-viscosity resins like PC to minimize residence time and avoid excessive shear heat. The S-136H mirror-polished die is machined to eliminate internal dead corners where material could stagnate and carbonize.

On the operator side, maintaining correct drying procedures and barrel temperature settings within the recommended 270–300°C range is essential.

Yes. Polycarbonate and PMMA are both amorphous, high-viscosity transparent resins with nearly identical screw design requirements — deep metering channels, long transition zones, and low compression ratios.

According to industry screw design guidelines, both materials call for a gradual-type single screw with compression ratios in the 2.0–2.6 range. This means the same screw and barrel can process both materials without mechanical changeover.

Switching between PC and PMMA requires adjusting barrel and die temperatures, purging the system, and verifying process parameters — a routine procedure, not a production-line reconfiguration.
