Changzhou Rongyu Roller Manufacture is presented as a source-reviewed supplier profile centered on Embossing and patterned rollers, with company-published capability separated from buyer-side verification requirements.
Changzhou Rongyu Roller Manufacture Co., Ltd. is an industrial-roll manufacturer and repair provider in Wujin District, Changzhou, Jiangsu. Its official website says the company was built in 1990 and operates an 18,000-square-metre site with more than 80 large precision machine tools, two imported engraving machines and a German photographic plate system. These dates and scale figures are company statements and should be checked against the current business licence, equipment register and an on-site audit. The range covers embossing, mirror, matte, anilox, calender, guide, chrome-plated polished and heating-roll components for paper, plastics, packaging and printing, textiles, nonwovens, metals, machinery and composite-material lines. The China Composites Expo listing misspells the English name as CHANGZHOU RONGYU ROOL MANUFACTURING CO., LTD.; its Chinese name, domain, phone and product scope match the official website, so this page consolidates the records 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 Rongyu Roller Manufacture Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changzhou Rongyu Roller Manufacture Embossing and patterned rollers.” 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 Rongyu Roller Manufacture 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 product directory lists patterned-roll samples, matte rolls, calender rolls, bending rolls, heating-roll shells, anilox rolls, pairing rolls, embossing rolls and super-mirror rolls. The China Composites Expo profile also identifies guide, smooth and chrome-plated polished rolls, plus cold and hot grinding or repair for paper calender, press and coating-backup rollers. For carbon fiber, prepreg, film, nonwoven or another continuous-web line, an RFQ should first define roll function and station, web and resin system, working width and line speed, operating temperature and pressure, allowable tension variation, then body and journal materials, heat treatment, face length, diameter, wall thickness, bearing interfaces, load, deflection and design life. Drawings and acceptance criteria should specify roundness, cylindricity, straightness, concentricity, total indicated runout, crown profile, Ra/Rz roughness, hardness, coating or plating type, thickness, adhesion, corrosion resistance and balance grade. Heated or cooled rolls additionally need medium, pressure, flow, temperature uniformity, thermal deformation and sealing requirements. Mirror rolls require an agreed roughness and gloss test method; embossing or anilox rolls require CAD or a physical master, repeat length, seam criteria, line count, depth, cell volume and an approved trial impression. Carbon-fiber and sensitive-web applications should also validate low runout, tension stability, fiber snagging and abrasion, conductive debris and cleanliness control. Repair RFQs should document incoming dimensions, remaining wall and coating, crack or NDT condition, and pre/post-repair measurements. FAT should cover material and heat-treatment records, dimensions and geometry, surface and coating reports, balancing, NDT and, where applicable, a thermal run or trial impression. Packaging should define lift points, journal protection, corrosion and moisture protection, supports and locking. Official pages refer to both Panjia Town and Lijia Town; the current contact page gives No. 777 Yangjia Village, Qinxiang Village Committee, Lijia Town. Confirm the actual manufacturing, invoicing and dispatch locations in writing before an audit, contract, payment or shipment.
Evaluate Changzhou Rongyu Roller Manufacture Co., Ltd. as a potential composite manufacturing equipment supplier for Embossing and patterned rollers, verify the public evidence and prepare a comparable RFQ.
Changzhou Rongyu Roller Manufacture 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 Mirror and super-mirror rollers, 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 Rongyu Roller Manufacture Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Changzhou Rongyu Roller Manufacture Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.
Changzhou Rongyu Roller Manufacture Co., Ltd. publishes Roll engineering and precision machining 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 Pattern engraving and embossing-roll manufacturing 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, Mirror, matte and anilox surface finishing 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.
Buyers evaluating Chrome plating, polishing and surface refurbishment should connect the process claim to evidence: an equipment list, controlled procedure, representative report, production photograph or witnessed sample may each answer a different risk. Changzhou Rongyu Roller Manufacture Co., Ltd. should also explain how the result is checked before release and recorded for the shipment.
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 Rongyu Roller Manufacture 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 Rongyu Roller Manufacture 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 Rongyu Roller Manufacture 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 Rongyu Roller Manufacture Co., Ltd.'s source record currently includes Official Rongyu Company Profile, Official Rongyu Product Directory, Official Rongyu Contact Page, China Composites Expo Exhibitor Profile. 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.

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.
