Changzhou Sinajet Science and Technology is presented as a source-reviewed supplier profile centered on DG/DH Series digital cutters, with company-published capability separated from buyer-side verification requirements.
Changzhou Sinajet Science and Technology Co., Ltd. is based in Changzhou, Jiangsu and develops intelligent plotting and cutting equipment plus custom production lines for non-metallic materials. Its China Composites Expo profile says the company was established in 2007, has received more than 200 patent grants with 70 currently valid, and is recognized as a national-level specialized and innovative 'Little Giant'; the English corporate site instead traces its activity to 2006. The current website serves textile and apparel, packaging, automotive interiors, furniture and composites and publishes DG/DH and DM digital cutters plus a 3D-CNC ultrasonic cutting machine. The date discrepancy, patent counts, recognition and performance statements are company- or organizer-published and have not been independently verified by GetFRP.

This procurement profile is built for plant owners and process engineers comparing production scope, controls, commissioning responsibility and lifecycle support. It organizes Changzhou Sinajet Science and Technology Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changzhou Sinajet Science and Technology DG/DH Series digital cutters.” 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 Sinajet Science and Technology Co., Ltd. currently lists 8 product or service groups and 6 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.
Sinajet's official composites directory lists DG/DH and DM digital cutters and a 3D-CNC ultrasonic cutting machine. Its composite solutions address flexible carbon-, glass- and aramid-fiber materials and include wind-blade cutting, heavy-roll automatic feeding, automotive PVB-film ultrasonic wire spreading and cutting, and other custom applications. The company publishes circular-, oscillating- and ultrasonic-knife tools together with modules, control and nesting software, vision scanning and automatic feeding. Published maximum cutting speeds are specific solution statements and must not be generalized to every machine. Equipment buyers should qualify the exact quoted model's working width and length; single- or multi-ply capacity and maximum thickness; supported fibers and prepreg state; tool configuration; positioning and repeatability; feed tension and alignment; dust and loose-fiber control; combustible-dust safety requirements; electrical supply; current CE or UL documents for the model and manufacturing site; software licensing; FAT/SAT acceptance criteria; installation and training; spares; warranty; and destination support.
No company-level certification is listed on this profile.
Evaluate Changzhou Sinajet Science and Technology Co., Ltd. as a potential composite manufacturing equipment supplier for DG/DH Series digital cutters, verify the public evidence and prepare a comparable RFQ.
Changzhou Sinajet Science and Technology 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 DM Series digital cutters, 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 Sinajet Science and Technology 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 Sinajet Science and Technology 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.
A useful RFQ for 3D-CNC ultrasonic cutting machines should describe the buyer's application without disclosing unnecessary proprietary detail, then state the measurable product requirements. Compare Changzhou Sinajet Science and Technology Co., Ltd.'s response against the same dimensions, quantity, inspection, documentation, Incoterm and delivery assumptions used for every shortlisted supplier.
Changzhou Sinajet Science and Technology Co., Ltd. publishes Digital cutting of carbon-, glass- and aramid-fiber fabrics 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 Multi-ply, roll-to-sheet and continuously fed cutting 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, 3D-CNC ultrasonic cutting 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 Wind-blade ply nesting and cutting 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 Sinajet Science and Technology 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 Sinajet Science and Technology 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 Sinajet Science and Technology 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 Sinajet Science and Technology 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 Sinajet Science and Technology Co., Ltd.'s source record currently includes Sinajet Official Website & Company Profile, Composite Cutting Equipment Directory, Composite Industry Solutions, Cutting Modules & Tools. 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.
No company-level certification is presently listed in the reviewed profile. That does not prove that no document exists, but it means the RFQ should ask for the quality-system certificate and every product-specific test or approval needed by the buyer rather than assuming a certification from market reputation.
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.
