Changzhou Keren Machine is presented as a source-reviewed supplier profile centered on Carbon-fiber and high-performance-fiber winding, with company-published capability separated from buyer-side verification requirements.
Changzhou Keren Machine Co., Ltd. is a winding-equipment manufacturer in Wujin District, Changzhou, Jiangsu. Its official website dates the company to 2008 and presents dedicated take-up, CNC-servo, variable-frequency, high-speed and automatic roll-changing equipment for carbon fiber, glass fiber, aramid, UHMWPE, basalt and other high-performance fibers, alongside winders for filter media, films, tapes and electronic carrier tape. The China Composites Expo 2025 directory lists the company at booth 7L33. The expo uses CHANGZHOU KEREN MACHINERY FACTORY CO., LTD., while the official English footer uses Changzhou Keren Machine Co., Ltd.; both records carry the same Chinese company name, domain, Changzhou contacts and product set, so this page consolidates them into one supplier identity.

This procurement profile is built for plant owners and process engineers comparing production scope, controls, commissioning responsibility and lifecycle support. It organizes Changzhou Keren Machine Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changzhou Keren Machine Carbon-fiber and high-performance-fiber winding.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.
Changzhou Keren Machine Co., Ltd. currently lists 8 product or service groups and 7 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.
The official English carbon-fiber winder page gives example specifications of variable-frequency or servo drive, 100–20,000 dtex, 216/230/290/330 mm bobbin length with other sizes optional, 100–300 mm traverse, a 300 mm spindle diameter, winding speed up to 400 m/min to customer requirements, and electronically adjustable tension. It also describes a lower-friction design intended to reduce fuzz on fine high-performance fibers. These are supplier-published values for one example machine and should not be generalized across the range. The page lists a one-set minimum order, wooden-case packing, a 30% down payment and a USD price band, showing that the website carries international inquiry terms; price, lead time, payment and configuration still require a project-specific formal offer. A winder RFQ should define fiber type, maker and grade, tow or dtex/tex, sizing and surface sensitivity, line speed, tension range, accuracy and variation, number of positions, tube bore and length, full-package diameter and weight, traverse stroke, pitch and package shape, winding ratio, drive and controls, plus automatic roll change, joining or cutting, broken-yarn detection, static control, dust and conductive carbon-fiber debris management. It should also set power and air, PLC/HMI and data interfaces, recipes and traceability, alarms, interlocks, guarding and applicable GB, CE or UL requirements. The site's reference to three explosion-protection schemes must be converted into a defined hazardous zone, gas or dust group, temperature class and applicable CN Ex, ATEX or IECEx certificate scope; a product description is not acceptance evidence. Buyers should trial the actual fiber and complete FAT covering calibrated tension and speed measurement, continuous running, full-package build, fuzz and waste criteria, then agree SAT, drawings and manuals, spares, installation, training, warranty and remote or on-site service. The homepage claims RMB 10 million registered capital, 50 technical employees and supply relationships with Sinopec and other named organizations; these require revalidation through the business licence, workforce or organization records, orders or customer-verifiable references. A 2021 official news item announced a new 10,000-square-metre base at No. 73 Gantang Road, Lijia Town, Wujin District, while the current contact footer still lists Building 3, Chengdong Industrial Park, Hebei Village, Jiangdong Road. The actual manufacturing, invoicing and dispatch addresses should be confirmed in writing before an audit, contract, payment or shipment.
Evaluate Changzhou Keren Machine Co., Ltd. as a potential composite manufacturing equipment supplier for Carbon-fiber and high-performance-fiber winding machines, verify the public evidence and prepare a comparable RFQ.
Changzhou Keren Machine Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.
For Glass-fiber monofilament winding equipment, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Changzhou Keren Machine Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
Changzhou Keren Machine Co., Ltd. publishes Specialty-fiber take-up and precision traverse winding as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.
The relevance of Electronic tension adjustment and constant-tension winding depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, CNC servo, variable-frequency and DC brushless drive integration is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.
Changzhou Keren Machine Co., Ltd.: The listed equipment can form part of a new production line, but machine selection should start from the product envelope, material system, throughput, utility and quality requirements. Ask the supplier to define every included station and the responsibility boundary for tooling, controls, guarding and downstream handling.
Changzhou Keren Machine Co., Ltd.: For an expansion project, the buyer should document interfaces with existing creels, molds, heaters, cutters, extraction, material handling and plant controls. A factory acceptance test should use representative materials and demonstrate the agreed output and quality measures rather than only showing that individual motors run.
Changzhou Keren Machine Co., Ltd.: Equipment value depends on installation, training, spares and troubleshooting after shipment. Confirm remote and on-site support, language, response time, software access, electrical documentation, consumables and the list of critical components that can be sourced in the destination market.
Changzhou Keren Machine Co., Ltd.'s source record currently includes Official Keren Company Profile, Official Keren English Product Directory, Official Carbon-Fiber Winder Product Page, Official Keren Contact Page. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
The profile lists 2 company-published certification or test references. A listing is not the same as validation: request the complete current document, issuer, legal holder, production site, product and grade scope, standard edition, report specimen and validity date before citing it in a project or purchase order.
GetFRP last recorded a public-source review date of 2026-08-13. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.

Open catalog
Nanjing Haoli Hydraulic Equipment Co., Ltd. states that it was founded in 1999 and entered the composites field in 2000. Its current official catalog covers hydraulic, servo-hydraulic and caterpillar-puller pultrusion machines plus pultrusion-winding, resin-injection, automatic cut-off, mat-cutting, take-up, braided-pultrusion cable-conduit and die equipment. The China Composites Expo N directory supports the exhibitor identity and FRP pultrusion-equipment scope. Haoli sells the machinery, tooling and process support used to manufacture composite profiles. The website's statement that a machine can pull glass- or carbon-fiber sections describes compatible workpieces; it is not evidence that Haoli supplies carbon fiber, fiberglass, pultruded profiles, conduits or other finished composites. GetFRP therefore does not assign material or finished-product demand keywords to this equipment profile.
Nabertherm Ltd. (Shanghai), identified in Chinese exhibition material as Nabertherm's Shanghai industrial-furnace company, is the China sales-company entry published on the current Nabertherm website. The reviewed official navigation covers air-circulation and drying ovens, radiation-heated chamber furnaces, high-temperature solutions, protective-gas and vacuum systems, laboratory muffle and tube furnaces, debinding and sintering systems, melting and holding furnaces, custom furnace engineering and process-control documentation. The China Composites Expo N directory independently supports the Shanghai exhibitor identity. This is an equipment profile: carbon fiber, fiberglass, resin, ceramic, metal powder or any other workpiece processed in a furnace is not a material manufactured by Nabertherm. The exhibition category also is not evidence that the Shanghai entity offers composite-curing autoclaves, so GetFRP does not publish an autoclave product or inject material-product keywords.
Lianyungang Weide Composite Materials Facilities Co., Ltd. says on its current official website that it was established in 2001 and develops and manufactures composite-production equipment. The published range covers continuous-filament-winding FRP pipe lines, high-pressure hydrogen-cylinder winding lines, four-axis and horizontal winding machines, high-pressure epoxy-pipe lines, centrifugal-casting GRP pipe lines, lighting-pole lines and supporting manipulators, curing ovens, resin-supply, intelligent feeding, conveying, joint-making and quality-assurance systems. China Composites Expo's L directory lists the matching exhibitor. Weide sells the machinery used to make pipes, cylinders and poles; those outputs are not presented as Weide-manufactured FRP or carbon-fiber products. GetFRP therefore excludes reinforcement, FRP-pipe and finished-cylinder supplier keywords. Capacity, performance, import-substitution, service-life and mechanical-property statements are supplier claims that must be validated against the quoted configuration, representative trials, FAT, SAT and contractual acceptance records.
