From machined components to assembled products, AUTOWIN brings materials, manufacturing, quality checks and private-label packaging together for distributors, importers and OEM brands.
Founded in 2004, Ningbo Sinppa Technology Co., Ltd. combines non-ferrous metal processing with machining, casting, molding, hose production and assembly. We connect these capabilities to the air service, tire service and car wash products your customers use every day.
Meet AUTOWINStart with an existing product range or send a drawing, sample or specification. We review the materials, connections, performance requirements and packaging for your project.
Brass machining, hose production and assembly support air hose fittings, compressed air fittings and air blow guns. Specify the connection profile, thread, hose size and operating conditions for a compatible assembly.
Metal components, molded handles and functional assembly support tire pressure gauges, tire inflators, valve tools and tire repair kits. Product specifications and private-label presentation are reviewed together.
Machined connections, molded housings and controlled assembly support each pressure washer gun, foam lance and accessory. Review pressure washer nozzles, pressure washer hose fittings and connector compatibility before production.
Manufacturing routes are selected for the component material, geometry, finish and application. Explore each process to see how it supports your sourcing requirements.
Turning, drilling and threading for air fittings, air hose connectors, coupler bodies and valve components. Material and thread requirements are reviewed against the approved specification.
Machined metal and engineering-plastic components based on drawings or samples. Critical dimensions, mating surfaces and inspection points are identified before repeat production.
Cast housings and shaped metal parts, with secondary machining and finishing where required. Alloy, tooling and appearance requirements are reviewed as part of the project.
Molded handles, housings and protective components for air blow gun, tire service and pressure washer applications. Resin, color, tooling and fit are specified for the intended product.
Finishing, marking and assembly bring metal, plastic and sealing components together. The assembly sequence and functional checks follow the approved product requirements.
Labels, color boxes, blister packs, kits and export cartons help prepare products for distributor and retail channels. Artwork, pack quantities and labeling are confirmed before production.
A fitting, a gauge and a spray gun have different inspection needs. We define the checks around the approved drawing, sample and specification, with records to support repeat orders.
Inspection & TraceabilityReview material requirements, critical dimensions, thread forms and mating features for fittings, cast parts and machined components.
Specify applicable pressure, sealing and functional checks for compressed-air and pressure-washer assemblies. Test conditions are agreed for the selected product.
For a digital tire gauge or digital tire inflator, confirm the measurement range, units, accuracy requirement and verification method before sample approval.
Check labels, kit contents, pack quantities and carton identification against the order. Keep the agreed inspection and packing records for follow-up.
Send the product reference, drawing or sample, quantities, application and destination market.
Review materials, tooling, specifications, packaging, MOQ and the proposed production schedule.
Check fit, function, finish and branding. Confirm the specification and packaging before production.
Follow the agreed production and inspection plan, then prepare export packaging and shipment documents.
Have a drawing, an existing product or a private-label range in mind?
Explore OEM / ODM supportUseful details to prepare your product brief.
Browse product cataloguesYes. AUTOWIN supports OEM, ODM and private-label projects across these product ranges. Depending on the product, options can include material, finish, color, markings, kit contents and packaging. Send the product reference and target quantity so we can confirm the available options, MOQ and tooling requirements.
For an air hose coupler or fitting, specify the interchange profile, thread type and size, material and required operating conditions. For a compressed air hose assembly, also provide the inside diameter, length, hose material and end connections. If you need a retractable air hose reel, include the hose specification and mounting requirements. Matching thread size alone does not confirm coupling compatibility.
We can review customization against the selected model. Share the pressure range, display units, accuracy requirement, chuck or connection type, hose specification, branding and packaging. The agreed sample and specification establish the requirements for production and verification.
Provide the required operating pressure and temperature, flow requirement, inlet and outlet connections, and the machine or accessory interface. For pressure washer quick connect fittings, confirm the connection size and mating components. A foam cannon car wash project should also define the bottle, connector, branding and intended application. Compatibility is reviewed for the complete assembly.
Yes. We can review a branded kit based on the selected components and packaging. Specify the contents for a tubeless tire repair kit or tire valve stem tool set, quantities per pack, labeling and destination market. The final kit configuration, application instructions and commercial terms are confirmed for the order.
These depend on the product, material, customization, tooling, packaging and order quantity. An existing product with custom packaging may have different requirements from a new molded or cast component. Send your reference, specifications and quantity for a project-specific quotation and schedule.
Send a drawing, sample reference or product list. Include the quantity, specifications, branding and destination market so our team can review the right manufacturing and supply options.
