Engineering your exact hydraulic cylinder — from concept drawing to production-ready unit — with full confidentiality and competitive pricing
OEM (Original Equipment Manufacturer) service means we manufacture hydraulic cylinders exactly to your engineering drawings, part numbers, and specifications — branded as your product, delivered to your standards. You own the design; we provide the precision manufacturing capability to bring it to life at scale.
ODM (Original Design Manufacturer) service goes a step further: our engineering team collaborates with you to develop the cylinder design from your functional requirements. We handle the mechanical engineering, material selection, prototype validation, and production tooling — you receive a finished, validated cylinder ready for integration into your machine or system.
Whether you need 10 prototype units or 10,000 production cylinders, Hengshui's OEM/ODM team delivers with full documentation, traceability, and strict confidentiality under NDA.
Submit your 2D drawings (DXF/DWG) or 3D models (STEP/IGES), and our engineers will perform a detailed manufacturability review within 48 hours. We flag any potential issues before production begins, saving you time and revision costs.
Our metallurgical team recommends the optimal steel grades, seal compounds, and surface treatments for your application — balancing performance requirements against cost targets. We source verified materials from approved domestic and imported suppliers.
We always recommend a prototype phase before committing to a full production run. Prototype units are manufactured under the same conditions as production parts, fully tested, and shipped to you for functional validation and approval — reducing rework risk significantly.
Cylinders can be manufactured under your brand identity — nameplate engraving, custom colour coding, part number stamping, and label artwork are all accommodated. Your customers will see your brand, not ours.
All OEM customer drawings, specifications, and business information are protected under signed non-disclosure agreements before any technical exchange takes place. Access to customer IP is restricted to the engineers directly working on your project. Your competitive advantage stays with you.
Submit your application requirements, operating parameters, and quantity targets via our enquiry form or email. Our team responds within 24 hours.
Our Chief Engineer reviews your requirements and produces a preliminary design proposal, including bore/stroke selection, material recommendation, and working pressure confirmation.
Upon design approval, we manufacture 1–5 prototype units using full production processes. Lead time: 15–25 working days depending on complexity.
Prototype units are shipped to you for functional testing and approval. Our engineers remain available for technical consultation throughout your evaluation phase.
Once prototype approval is confirmed, we schedule your production run. Full production lead times are typically 30–60 days depending on order volume.
Finished cylinders are inspected, pressure-tested, packed per your requirements, and shipped via your preferred freight method with full documentation including material certs and test reports.
