Custom Screw Design Services
Engineered precisely for your material, your machine, and your production goals.
Engineered precisely for your material, your machine, and your production goals.
Off-the-shelf screws compromise on performance. Every polymer, filler ratio, and output target demands a unique screw geometry. Our custom design service starts from your specific process parameters and delivers a screw solution optimized for your exact application.
Our in-house engineering team analyzes your material rheology, barrel specifications, desired throughput, and quality requirements. We then design flight depth progressions, compression ratios, mixing elements, and surface treatments that maximize your production efficiency while extending component service life.

Custom Solutions Delivered
A structured workflow ensures every custom screw meets your exact specifications with no surprises.
We evaluate your material type, output targets, temperature range, and machine specifications to define the optimal screw geometry.
Our engineers create detailed 3D models with optimized flight depth, compression ratio, and mixing sections tailored to your process.
Advanced CNC and 5-axis machining centers produce your screw with precision machining and dimensional inspection for consistent performance.
Every custom screw undergoes hardness testing, dimensional inspection, and surface finish verification before shipping.
Fast worldwide shipping with ongoing technical support. We help with installation guidance and process optimization.
We select the optimal material based on your processing conditions, wear factors, and budget requirements.
High nitrogen absorption capacity with excellent wear resistance. Ideal for general-purpose extrusion applications with surface hardness up to HV 950-1050.
Centrifugally cast alloy layer provides improved wear and corrosion resistance. Well-suited for processing abrasive or corrosive materials like glass-fiber reinforced compounds.
High-speed tool steel with outstanding red hardness and wear resistance. Used for high-performance screws processing demanding materials at elevated temperatures.
Tungsten carbide or nickel-based alloy spray welding applied to screw flights for maximum abrasion resistance in highly filled compound processing.
Each material and process presents unique challenges. We design screw geometries that solve the specific issues you face.
Optimized mixing and venting design for WPC profiles with high wood fiber content up to 70%.
Low-shear geometry prevents degradation while maintaining thorough gelation and homogeneous melt quality.
Precision temperature control and special mixing sections for uniform foaming agent distribution.
Gentle processing with optimized compression ratio to prevent material degradation while achieving full plasticization.
Specialized barrier screw design for co-extrusion of PE core layers with consistent thickness control.
We combine deep plastics processing knowledge with precision manufacturing capabilities to deliver screws that perform from day one.
