Pipe, Profile, PPR, and WPC Lines for the Building Trade

Building and construction site context — JURRY supplies extrusion lines for the PVC pipe, window profile, PPR, and WPC materials that go into projects like this one.

Who We Build For

We do not sell to first-time owners, and we tell our sales team to walk away if we cannot match the buyer's certification spec. Because the lines we ship expect a real schedule and a real certification file. Our technical director, plant manager, supply chain manager, and quality manager clients tell us the same thing: a line without paperwork is a line they cannot put on the floor.

01Dimensional Tolerance at the 0.1mm Level

PVC window profile cross-sections of the type produced on JURRY window profile extrusion lines. Dimensional tolerance at the 0.1mm level ensures proper sealing.

When a sliding window profile is off by 0.3mm on the outer frame leg, the EPDM gasket does not seal. We have seen the failure mode on audits: water ingress at the sill. Because sealing depends on geometry invisible on a flat drawing, we hold profile dies to ±0.1mm and document IQC samples per shift. The dimensional record is the same record your quality manager hands to the building inspector, and we publish the approach in our knowledge base so the math is not proprietary.

PVC window profile cross-sections of the type produced on JURRY window profile extrusion lines. Final tolerance is verified against your national window-standard spec.

Our die head for profiles uses a 3D-designed, CNC-cut mandrel. The downstream vacuum tank and cooling tank are sized for the specific profile cross-section, not a generic length, so the calibration geometry matches the die geometry. Because vacuum drift is the most common cause of an off-spec profile, we ship vacuum gauges with calibration certificates.

Because your quality manager will be asked for the certificate, we issue a dimensional report with 10 measured points per profile. If you need tighter than ±0.1mm on a critical face, we adjust the die and re-run the FAT. We ship to ISO 9001:2015 quality systems and we hand you the dimensional record as part of the same file. The line is also built to the EU Machinery Directive 2006/42/EC and IEC 60204-1 electrical safety requirements, which is what lets us sign the CE declaration of conformity on your behalf.

02Doubling Output Without Doubling Budget

JURRY PVC/WPC line of the type installed for building-material manufacturers. Final layout is engineered to your factory footprint and downstream.

A developer needed double the output. We quoted the window profile extrusion line cost in three tiers, including the multi-cavity die option. We doubled their line speed from 12 m/min to 22 m/min by upgrading the extruder, replacing the single-cavity die with a twin-cavity die, and adding a second haul-off caterpillar. Capex was about 60 percent of a second line.

Because our buyers run on tight capex, we engineer for output-per-meter before footprint. Our parallel twin screw extruders deliver higher specific output at lower melt temperature, which lets us hold line speed without burning the profile. The profile extrusion line ramps to stable output in 90 minutes.

For greenfield sites, our profile extrusion line can be configured with a multi-cavity die for sliding and casement profiles from day one, with a downstream sizing table that handles both 60mm and 80mm series without a mechanical changeover. We design the upstream PVC conveying & mixing system so the throughput does not starve the extruder, and we connect it to your single screw extruders if you already have one running.

If your plant manager is being asked to double output without doubling budget, our answer is rarely "buy another line." The honest answer is usually a higher-output extruder, a multi-cavity die, and a downstream that does not bottleneck. We model the capex delta for you inside a week, and we usually quote window profile extrusion line cost in three tiers so your finance team has a real comparison.

03Diameter Changeover in Under 4 Hours

A Riyadh plant manager was losing 9 hours every Friday switching from small-bore cold water to large-bore drainage. Because changeover is where OEE dies, we engineered it into the line. Our pipe line ships with a modular die head for pipes on a quick-change cart and a PLC with 200 recipes.

UPVC pipes of the type produced on JURRY PVC pipe extrusion lines. Actual line configuration is built to your diameter and pressure-class spec.

The recipe memory covers extruder RPM, barrel zones, melt pressure, haul-off speed, vacuum tank vacuum, cutter length, and stacker count. When the operator loads recipe #17, the line ramps to stable in under 90 minutes, including the diameter changeover and the vacuum calibration re-set. From the operator's seat it is a single menu, not a checklist. Our pipe extrusion lines cover the full small-bore to large-bore diameter range and we hand you the recipe library on a USB drive at the FAT.

Because most of our customers run two diameters per shift, we sized the conical twin screw extruders for a wide RPM window. We publish PVC pipe extrusion machine price tiers per diameter class so the per-tonne cost drops as you add SKUs.

04High-Filler CaCO3 Formulations That Survive the Tensile Test

PVC door frames and panels of the type produced on a JURRY PVC door frame making machine. Recipe library for frame extrusion ships with every line.

CaCO3 spikes are the most common reason we get calls to push the filler rate. Because pushing filler past the recipe ceiling cracks profiles in the field, we publish the ceiling we have validated rather than letting the buyer guess. Our window profile recipes hold 30-60 phr CaCO3 with TiO2 at 4-8 phr, and we share tensile data before commercial runs.

The compounding side is where most factories lose the cost saving. Our PVC conveying & mixing system and online mixing system handle 30-60 phr filler without low-shear dispersion issues. Because we ship the recipe with the line, the operator does not need a PhD in rheology to keep the profile inside EN 12608 or ASTM D1785 spec.

Because we are asked about filler ceilings on every technical call, the answer we give is the same one our QC lab uses: 30-60 phr for window profile, 20-40 phr for pressure pipe, and 40-80 phr for drainage and conduit. We will not recommend outside that range without a tensile test in our lab. The line is built to ISO 1452 PVC-U pressure-pipe standards and we hand you the PVC door frame making machine recipe sheet on the same USB drive we use for pipe recipes. Our PVC pipe extrusion machine price reflects the diameter class and downstream length, and we publish the per-class table in the FAT file.

05Certification — CE, SASO, IECEE

PPR hot and cold water pipes of the type produced on a JURRY PPR pipe manufacturing plant. Pressure-class certification depends on the recipe and the QC records.

Certification is the difference between a line that clears customs and a line stuck in a bonded warehouse for six weeks. Because we ship to 35+ countries, our compliance team has built a CE / SASO / IECEE file template that we attach to every line that touches an EU, GCC, or IECEE market. The file includes the CE declaration under EU Machinery Directive 2006/42/EC, the IEC 60204-1 electrical safety file, and the SASO Saudi Standards CoC package.

For Saudi-bound shipments we host the SASO inspector at our Shanghai workshop for a 1-2 day FAT. We forward the original CoC, test reports, and invoice set with the shipment, and our compliance team stays on email for the first 90 days. We publish our compliance approach in our news feed.

Because most buyers also need product-side certification, not just line-side, we hand you the recipe-specific test data for EN 61386 conduit and ASTM D1785 PVC pipe pressure ratings alongside the line documentation. Our buyers have cleared building-standard audits across the EU, GCC, and Southeast Asia. If you need a jurisdiction we have not templated, our compliance team drafts one inside two weeks.
