Comprehensive Sourcing Guide

Double Stage Plastic Granulator Supplier Concentration and Factory Types

Suppliers of double stage plastic granulators on this page are concentrated in China, with listed results pointing to Shandong and Jiangsu as active provinces for this equipment. Shandong-based listings emphasize a broad hose and pipe extrusion portfolio alongside granulator machines, while Jiangsu-based listings center more tightly on plastic recycling machinery, film washing lines, and pelletizing plants. These provincial clusters matter because surrounding component suppliers, screw and barrel machinists, and experienced technicians tend to accumulate where granulator manufacturing is already dense, which can shorten build times and simplify spare part sourcing after commissioning.

Supplier types vary meaningfully. Some listings identify pure Manufacturer/Factory entities, others are Trading Company combined with manufacturing, and one listing uses a Combined designation. A factory-type supplier is generally better positioned to discuss screw design, gearbox selection, and vacuum degassing configuration in technical detail, whereas a trading company may aggregate multiple production lines and offer wider machine selection but add a communication layer. Reviewing the main products field is a practical filter: a supplier whose catalog is dominated by recycling machinery and pelletizing lines will understand double stage configurations more deeply than one whose core business is a different machine family. Note also that research and development capability labels differ across listings, with some suppliers advertising OEM capacity, some promoting their own brand, and others listing ODM, which signals different customization starting points.

How to Verify Double Stage Plastic Granulator Suppliers

Verification should start with the third-party credentials actually displayed on the listing. Several suppliers in these results carry verification from recognized inspection bodies such as BV or SGS, which indicates a company-level audit rather than a product-level certification, so ask precisely what was inspected and when. System certifications also differ: one Shandong listing shows ISO 14000 and QC 080000, while a Jiangsu listing shows ISO 9000 and ISO 9001. An environmental management standard and a quality management standard answer different questions, so match the certificate to your concern. Individual products on this page list CE certification, but confirm the certificate covers the specific granulator model, not just the product family.

Beyond documents, request video or live factory inspection focused on the double stage assembly floor, since the two-extruder configuration, the filter changer, and the pelletizing die are where build quality becomes visible. Ask for the factory's machine model numbering system; the listings here show structured model ranges such as RSS-85 through RSS-200 and RSJ45 through RSJ200, and a coherent model ladder suggests established production. Verify the machine attributes in writing: the sample products list single-screw designs, water ring pelletizing, electromagnetic heaters, PLC control, and inverter drives, and one spec sheet names Siemens motors with a 38crmoala screw material. Any attribute not stated in the listing should be confirmed before deposit, and warranty terms, shown as one year on one listing, should be checked case by case.

What to Compare Across Double Stage Plastic Granulator Suppliers

Build a comparison sheet using the attributes visible on supplier listings. Response time is one measurable difference: recorded average response speeds on this page range from under two hours to more than six hours, which during troubleshooting and pre-sales engineering matters as much as price. Lead times also vary, with listings showing figures of roughly 45 days and 60 days, so align the supplier's stated lead time with your installation schedule and confirm whether the clock starts at deposit or at drawing approval. Company type, location, verification body, and system certifications give you a second axis for filtering out suppliers who cannot meet your compliance baseline.

Compare the machines themselves using the spec sheets. Capacity claims on this page range from an 80-500 kg/h granulator to a 150-1000 kg/h double stage line, and one film granulator lists model sizes up to a 200mm screw with a 33:1 L/D ratio and screw speeds of 1-120 rpm. Confirm throughput figures against your actual feedstock, since dirty PE film and rigid regrind behave differently through a double stage line. Note customization flags: several products say Customization Available while one explicitly says Non-Customized, so a buyer needing a tailored configuration should filter early on that field. Voltage options, palletizing method, degassing vent availability, and after-warranty support arrangements, listed as video and online support on one product, complete a meaningful side-by-side comparison before quoting begins.

Common Double Stage Plastic Granulator Sourcing Risks

The most frequent risk is a capacity mismatch. Listings advertise throughputs such as 80-500 kg/h or 150-1000 kg/h, but these figures usually assume clean, pre-shredded, consistent feedstock. If your waste is wet film, heavily printed bags, or mixed rigidity material, the double stage's pre-cutting extruder and fine filtration must be configured differently, and failing to disclose the real input can leave you with a machine that cannot hold the promised output. A second risk is specification drift between quotation and production: attributes such as vacuum degassing, which one listing marks as optional, or motor brands, which one lists as Siemens or customized, are easy places for a supplier to substitute cheaper components unless the purchase contract enumerates them.

Lead time risk deserves attention because this category shows substantial variation, including one listing with no lead time displayed at all and others at 45 or 60 days. Confirm the schedule in the contract with defined milestones for mechanical completion, inspection, and shipment. Packaging and shipping risk is real too; one listing specifies sea transport standard packing while another lists plastic stretch film, which is a thin barrier for a machine of this weight and should prompt a crate requirement. Finally, beware of non-customized machines when your application demands customization, and treat after-warranty support commitments, such as online and video technical support, as contract items with defined response expectations rather than verbal assurances.

Double Stage Plastic Granulator Regional Sourcing and Logistics

Because the verified listings sit in Shandong and Jiangsu, buyers can plan logistics around those two provinces. Jiangsu's coastal position near major Yangtze Delta ports generally simplifies container loading and may reduce inland transport legs, while Shandong also offers strong port access for heavy machinery shipments. A granulator of the dimensions shown in the listings, including one machine measuring roughly 10 by 2 by 3 meters and another line reaching 20 by 4 by 4 meters, will typically require flat rack or open top containers or breakbulk arrangements, so involve your freight forwarder before signing rather than after production. Ask each supplier which port they ship from and whether loading, lashing, and securing are included in the quoted price.

Confirm packing specification in writing, since one listing states sea transport standard pack and another lists only plastic stretch film; for ocean freight, request fumigated wooden crates with steel frames and moisture protection for the electrical cabinet. Shipping weight and dimensional drawings are essential for booking, and the model size you choose, from the smaller RSS units to the largest 200mm-screw lines, directly changes freight cost per machine. Time your order against production calendar congestion around Chinese holidays, when the displayed 45-60 day lead times can extend. For installation, ask whether the supplier dispatches an engineer or provides remote commissioning, and whether customs clearance documents, including a detailed packing list and HS classification support, will be supplied with the shipment.

Double Stage Plastic Granulator Commercial Terms and Order Planning

Commercial terms in this category vary widely, so anchor negotiations in the displayed data. Sample product pricing on this page ranges from a listed figure of about USD 30,000 for a PET granulator to roughly USD 54,000-56,000 for a double stage PP/PE pelletizing line, with another film granulator listed up to USD 140,000. These numbers are list prices, not quotes; configuration choices such as vacuum degassing, PLC control, motor brand, and capacity class will move the final figure. MOQ on the sampled products is one set, which is normal for capital machinery, so negotiation should focus on price, payment structure, and warranty rather than volume. Ask whether the supplier accepts escrow or platform-protected payment, since not every listing displays an escrow option.

Plan the order around the lead times shown, 45 and 60 days in these listings, plus time for pre-shipment inspection and ocean transit. Structure payment as a deposit with a balance tied to inspection or commissioning, and put the full technical specification sheet, including screw material, gearbox type, electrical components, and packing method, into the annex of the contract. Request the warranty in writing; one listing shows a one-year warranty with video and online support afterward. Finally, agree on spare parts, particularly screens, knife blades, and heater bands, in the first order, and confirm the response time commitment, which varies from under two to over six hours on this page, so support gaps do not stall your recycling operation.

FAQs

What is a Double Stage Plastic Granulator and when should I buy one?

A Double Stage Plastic Granulator uses two extrusion stages in series to degas, filter, and pelletize material in one continuous line. It suits contaminated or high-moisture feedstock such as washed film, bags, and bottles, where single-stage lines leave voids or impurities in pellets. For clean, pre-dried material, a single-screw granulator may be enough and cheaper to run.

What capacity can I expect from a double stage granulator line?

Listed models on this page cover roughly 80-500 kg per hour for PET pelletizing units and 150-1000 kg per hour for PP and PE recycling lines. Actual output depends on feedstock type, moisture content, and screen size, so ask each supplier to quote throughput for your specific material. Model series such as RSS-85 through RSS-200 indicate different size classes.

How much does a Double Stage Plastic Granulator cost?

Prices in the current listings range from about 30,000 US dollars for a compact PET granulator to 54,000-56,000 US dollars for double stage PP and PE pelletizing lines, with larger configured lines quoted up to 140,000 US dollars. Final pricing depends on capacity, automation level, and auxiliary equipment, so request itemized quotes before comparing suppliers.

What is the typical MOQ and lead time for these granulators?

The quoted products show a minimum order quantity of one set, which is standard for complete production lines. Lead times among the listed suppliers range from about 45 to 60 days after order confirmation, depending on factory schedule and customization level. Confirm the exact production window in your contract, including time for testing and sea transport packing.

Which certifications should I check before ordering a granulator?

Look for CE marking on the machine itself, which the listed products carry, plus supplier-level quality systems such as ISO 9001 or ISO 14000. Several suppliers on this page hold ISO 9000, ISO 14000, or QC 080000 certification, and independent verification by BV or SGS is shown for some. Always request valid certificate copies and confirm the certifying body is current.

Which regions do these granulator suppliers ship from?

The suppliers in these results are based in China, specifically Shandong and Jiangsu provinces, both established hubs for plastic recycling machinery. Jiangsu suppliers tend to focus on film, bottle washing, and pelletizing lines, while Shandong manufacturers also cover hose extrusion equipment. Sea transport standard packing is typical, so budget for container shipping and installation support at your site.

Can I customize voltage, materials, and configuration on a granulator line?

Yes, customization is listed as available on the quoted double stage granulators, and suppliers state voltage options such as 220V, 380V, 50Hz three-phase, or customer-specified configurations. You can also specify motor brands, electromagnetic heaters, PLC control, and vacuum degassing. Send your feedstock samples and plant power specification early so the supplier confirms feasibility before quoting.

How fast do these suppliers respond to inquiries?

Average response times in the current results range from about 1.9 to 6.2 hours, so most suppliers reply within one business day. Response speed usually reflects a sales team's availability rather than engineering depth, so follow up technical questions with a call or video meeting. Fast first replies should still be paired with detailed drawings and a written specification sheet.
