China Precise Extrusion Equipment Factory & Advanced Manufacturing Hub

BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) focuses exclusively on precision micro-extrusion lines where dimensional errors directly destroy functional yield. Unlike mass-volume commodity pipe extruders, our systems feature specialized screw aspect ratios (L/D 28:1 to 32:1), high-torque servo direct drives with zero mechanical backlash, Dynisco melt pressure monitoring systems, and digitally locked laser gauge puller feedback loops capable of maintaining tolerances within ±0.01 mm consistently.

Our vacuum cooling tanks use high-accuracy negative pressure regulation (-0.01 to -0.09 MPa) with electronic proportional valves and variable-frequency water ring pumps. Specially engineered turbulent water sprays prevent thermal laminar flow around the molten plastic sheath, avoiding asymmetric cross-sectional shrinkage and guaranteeing near-perfect circular concentricity across high hauling velocities.

Yes. We engineer turn-key 3-layer, 5-layer, and multi-layer co-extrusion crossheads. Every layer is served by a dedicated extruder whose melt delivery is calculated via finite element analysis (FEA) to balance shear heat and layer thickness ratios, ensuring total barrier permeation integrity complying with Euro 6 and EV fuel and vapor management requirements.

To prepare an engineering-grade layout, we require: detailed cross-sectional CAD drawings with target OD, ID, wall thickness, and tolerance limits; polymer datasheets (MFI, density, crystalline characteristics); target line speed (m/min) or kg/h output; downstream processing requirements (in-line continuous laser measurement, servo rotary cutting, or traverse displacement coiling); and your plant voltage/frequency.

Through our Global Service framework, BAOD provides full on-site dispatch of electrical and process engineers for line erection, PLC parameter tuning, and operational training. Furthermore, every machine is equipped with remote VPN diagnostic modules enabling our Jiangsu software engineering department to inspect drives and ladder logic within hours of a query.
