Pioneering Material Innovation Since 1993

Shanghai Omega Co. is a leading enterprise in the design and production of abrasion and corrosion-resistant screws, barrels, and extruders used in extruding, blow molding, and injection molding of rubber and plastic products.

Our strength lies in material development. We have introduced proprietary alloys comparable to those of renowned European manufacturers. For example, our high vanadium cast iron Ω102A alloy matches the performance of W&P’s 99.3 alloy.

Technical Support & Solutions

Addressing real-world extrusion challenges with proven engineering expertise.

Sheet Extrusion: Uneven Surface & Poor Gloss

Caused by inconsistent melt temperature, poor mixing, or worn screw/barrel. Omega’s bimetallic components ensure uniform plasticizing and extended service life, maintaining consistent output quality over time.

Profile Extrusion: Unbalanced Cooling

Results in warping and dimensional instability. Our precision-engineered screws provide stable melt delivery, reducing stress on downstream calibration and cooling.

Improving Dimensional Accuracy

Achieved through optimized screw design for consistent melt homogeneity and pressure control. Omega offers custom screw configurations tailored to your polymer and process.

Cleaning & Maintenance of Profile Molds

Regular cleaning with proper solvents and inspection for wear. Our durable liners reduce contamination buildup and extend maintenance intervals.

Grooves & Pits on Profile Surfaces

Often due to contaminated feed or abrasive fillers. Omega’s high vanadium iron liners offer superior resistance to abrasion and pitting.

Raw Material Selection for PVC Foamed Profiles

Critical for skin-core structure and cell uniformity. We advise on screw design to handle microcellular foaming agents and ensure proper dispersion.

BOPET Film Production Control

Requires precise melt temperature and viscosity control. Omega’s extruders deliver stable output for consistent film quality.

Conical Twin-Screw No-Load Test Run

Verify alignment, gear box operation, and motor performance before material feeding. Omega provides full commissioning support for new installations.
