US Engineers manufactures precision screw barrels and spare parts for plastic extrusion lines — and optimizes HDPE pipe and recycling lines for better output and lower power consumption. Based in Patiala, Punjab. Supplying manufacturers across India, UAE, Saudi Arabia, and Africa.
The Cost of Inefficiency
Every hour your line runs below potential, you are losing money. These are the exact pain points we solve — permanently, not temporarily.
Worn screws and barrels make your motor work significantly harder than it should. Every hour of inefficiency burns money you don't need to spend.
Degraded geometry means lower melt pressure, poor mixing and reduced throughput — your line never hits rated capacity.
Pipe wall irregularities, surface defects and dimensional inconsistency fail IS:4984 and EN 12201 quality checks.
Abrasive fillers and poorly selected materials accelerate wear beyond acceptable tolerances within 3,000 hours.
Emergency shutdowns, rework batches and unscheduled maintenance stall production for days — costing lakhs.
Poor melt homogeneity causes degradation, black specks and carbon contamination across the melt zone.
A WORN SCREW QUIETLY COSTS YOUR PLANT
LAKHS EVERY YEAR IN WASTED POWER & LOST PRODUCTION

Rooted in 20 Years of Industry Know-How
Part of GS Tanghi Industries — an established engineering group with over 20 years in the plastic extrusion industry in Punjab. The same experience, supplier relationships and technical know-how that built that business is what drives everything we make here.
We don't simply copy your old screw. We analyse your polymer, L/D ratio and output targets — then design geometry that delivers results.
All screws and barrels go through dimensional verification before dispatch. We provide documentation with every job so you know exactly what you're installing.
Based in Patiala, Punjab. We understand your machines, materials and urgency. Emergency parts delivery available pan India.
After installation, the difference shows up as lower amperage draw and better output — on your actual machine, not in a brochure. We encourage you to compare before and after.
Our Engineering Process
Every engagement follows a structured technical process — no guesswork, no generic solutions.
We start with a conversation — over WhatsApp or a call. You tell us your machine details, what's changed, and what you're seeing on the production floor. That's enough for us to get started.
Worn screws and barrels are measured and inspected. The wear pattern tells us the root cause — whether it's material selection, screw design, or how the machine is being run.
Screw geometry is redesigned for your specific resin grade, L/D ratio and output target. No generic replacements.
Machined, heat treated and surface finished to specification. Every component is checked before dispatch and ships with a job report so you know exactly what you're receiving.
Once the part reaches you, we stay on call. If you have questions during fitting or first run, we walk you through it over WhatsApp — until your line is running smoothly.
Industries & Applications Served
Exporting from India
HDPE pipe demand is growing rapidly across the Gulf and Africa — and so is the need for reliable, cost-effective screw barrels and extrusion spare parts. European and Chinese suppliers are expensive or inconsistent. We offer Indian precision manufacturing with direct communication, competitive pricing, and full technical support over WhatsApp.
Serving HDPE pipe and plastic processing plants across Dubai, Sharjah, Abu Dhabi and the Northern Emirates. Indian-made parts at a fraction of European cost.
Infrastructure growth across KSA, Qatar, Kuwait and Oman is driving HDPE pipe demand. We supply screw barrels and extrusion parts for plants serving these markets.
Rapid urbanisation across East, West and Southern Africa is creating strong demand for HDPE pipes for water and irrigation. We support manufacturers in these growing markets.
Competitive pricing compared to European suppliers. Better consistency than most Chinese alternatives. WhatsApp-accessible technical support. Fast shipping via air or sea freight.
Enquiries welcome from UAE, Saudi Arabia, Qatar, Kuwait, Oman, and all African markets
Send us your machine details and current screw/barrel specs — we'll respond with pricing and lead time.
Client Results
"After US Engineers looked at our screw design, our power consumption came down noticeably on our 90mm HDPE line. The machine is running smoother and the output is more consistent."
Rajinder Singh
— HDPE Pipe Manufacturer, Ludhiana
"We were getting 180 kg/hr on our recycling extruder. After their new screw, we're consistently hitting 240 kg/hr with no increase in motor load. Outstanding results."
Suresh Kumar
— Recycling Plant Owner, Jalandhar
"The barrel work they did on our line has held up very well. Service life has improved significantly compared to what we were getting before. Very professional team."
Harpreet Bhatia
— PP Pipe Extrusion Unit, Amritsar
No Equipment Needed
You don't need any special instruments. Everything below can be observed from your machine's own control panel and production floor.
Your extruder control panel shows a current reading (amps). If it's running higher than it used to for the same speed and material, your screw is working harder than it should — a clear sign of wear.
Weigh what your line produces in one hour. Compare to what it used to give or what the machine is rated for. A drop in output without changing anything else points to internal wear.
Rough surface, flow marks, pitting or streaks on your pipe or film are signs of poor melt quality — usually caused by worn screw geometry or temperature inconsistency.
Black specks, yellow or brown streaks, or burnt material during purge means polymer is sitting and degrading somewhere in the melt path — a screw or head geometry problem.
If your head pressure is lower than it used to be, or it fluctuates during a steady run, your screw is likely not building proper melt pressure — a sign of wear in the metering zone.
If your screw has been running continuously for several years with abrasive or filled materials and has never been checked, it almost certainly needs inspection — even if nothing seems obviously wrong yet.
