Production Flow

Each rail and screw follows a standardized production route with full traceability – from incoming raw material to final shipment. Consistent processes ensure repeatable quality for every batch.

1. Raw Material Incoming & Inspection

Steel bars and blanks are checked for hardness, composition and surface condition before entering production.
2. Cutting & Rough Machining

Materials are cut to length and rough machined to reserve accurate allowance for later grinding.
3. Heat Treatment / Hardening

Heat treatment improves hardness and wear resistance while controlling deformation within strict limits.
4. Precision Grinding & Milling

Rails, blocks and screw shafts are precision ground and milled to achieve straightness and dimensional accuracy.
5. Assembly & Preload Adjustment

Blocks, nuts and matched components are assembled, preloaded and tested for smooth running.
6. 100% Quality Inspection

Key parameters such as straightness, lead accuracy, roughness and preload are checked for every batch.
7. Anti-rust Oil & Packing

All parts receive anti-rust protection and export-grade packing suitable for long-distance shipment.
8. Warehouse & Shipment

Finished products are stored in a dedicated warehouse area and shipped by sea, air or courier.

Workshop Tour

Take a closer look at our dedicated workshops for linear guides, ball screws and custom machining. Each area is organized for efficient production and quality control.

Nanjing Tibi Ai Import and Export Trading Co., Ltd. factory production line 0

Linear Guide Workshop

Equipped with rail grinding lines, automatic chamfering machines and dust-controlled assembly areas, this workshop focuses on linear guides and blocks for various series and sizes.

From raw rails to assembled carriages, every step is monitored to keep stable accuracy and smooth movement for demanding automation applications.

Ball Screw Workshop

The ball screw workshop covers both rolled and precision ground ball screws. Critical processes such as thread forming, lead accuracy control and nut assembly are completed in-house.

Lead accuracy, surface roughness and preload are strictly controlled to meet different precision levels required by CNC, 3D printing and automation customers.

Machining & Assembly Area

CNC machining centers support non-standard end machining, custom flanges and complete unit assembly, including linear modules and screw-driven stages.

By finishing more work inside the factory, we help customers reduce assembly steps and shorten their own machine build time.

OEM/ODM

OEM / ODM – Custom Linear Motion Solutions

Flexible OEM and ODM services for linear guides, ball screws and related components, tailored to your brand and application.

OEM Production – Your Brand, Our Factory

For distributors, wholesalers and OEM partners, we provide stable batch production with your own branding and packing. Popular sizes can be arranged with safety stock to support fast local delivery.

Logo & Marking: Support laser marking on rails, blocks, screws and labels according to your brand guidelines.
Packing & Barcodes: Customized inner boxes, outer cartons and barcodes to match your warehouse system.
Stable Supply: Long-term production planning and safety stock for high-turnover items.
Confidential Cooperation: Protect customer drawings, prices and brand information with strict confidentiality.

ODM & Custom Projects

When standard models cannot fully match your machine design, our engineering team can work with you on customized linear motion solutions.

Custom Linear Guides

Non-standard rail lengths and hole patterns.
Special block dimensions or mounting interfaces.
Surface treatment options for different environments.
Adjustable preload and sealing options.

Custom Ball Screws

Special leads and diameters for unique applications.
Custom end machining according to your shaft drawings.
Different nut types, flanges and preload classes.
Matched support units, housings and couplings.

By understanding your machine structure, load conditions and working environment, we can recommend practical designs that balance performance, cost and delivery time.

How OEM / ODM Cooperation Works

A clear and transparent process helps both sides move from idea to stable mass production smoothly.

1. Requirement & Drawing Confirmation

Share your requirements, drawings, quantities and target markets. We will review feasibility and suggest options if needed.
2. Technical Evaluation & Quotation

Our engineers evaluate materials, processes and tolerances, and then provide a detailed quotation and lead time.
3. Sample Production & Testing

Samples are produced and tested in our factory, then sent to you for installation and on-machine verification.
4. Mass Production & Quality Control

After sample approval, we start batch production with the same process route and quality control plan.
5. Long-term Support & Re-order

We keep production records and inspection reports for repeat orders, and can adjust details based on your feedback.

Discuss Your OEM / ODM Project

Whether you are building your own brand or looking for a cost-effective alternative supplier, our team is ready to review your drawings and requirements.

You can send us your current models, photos or dimensional drawings, and we will offer a technical proposal and quotation.

R&D

R & D – Engineering Behind Precision

Dedicated R&D and engineering team focusing on linear motion technology, supporting both product optimization and customer projects.

Engineering Team

Our R&D and engineering team has long-term experience in linear guides, ball screws and related components. They work closely with production and quality departments to turn design concepts into stable, mass-producible products.

Experienced engineers with background in mechanical design and automation.
Familiar with common dimension standards in the linear motion industry.
Support for model selection and compatibility design in replacement projects.
Ability to interpret customer drawings and turn them into manufacturable solutions.

What We Focus On

R&D activities are not limited to new products. We continuously refine existing designs through testing and feedback from real applications.

Life & Load Performance

Optimizing raceway geometry and contact ratios.
Balancing dynamic load capacity with smooth movement.
Improving performance under vibration and repeated start–stop cycles.

Corrosion Resistance & Surface Treatment

Evaluating different materials for various environments.
Testing anti-rust coatings and surface treatments.
Designing suitable protection for high humidity or light chemical exposure.

Noise & Smoothness

Reducing running noise through ball circulation optimization.
Improving lubrication paths and sealing structures.
Ensuring smooth movement after long-distance transport and storage.

Co-Development with Customers

For key OEM and system integration projects, we welcome early-stage technical communication and joint development. By understanding your machine layout and application details, we can design more suitable linear motion solutions.

Early Involvement: Participate from concept or prototype stage to avoid later design changes.
Installation & Compatibility: Confirm mounting dimensions, preload levels and lubrication schemes together.
Sample Trials: Provide trial batches for on-machine testing and collect data for optimization.
Continuous Improvement: Adjust design details based on field feedback to enhance life and reliability.

With close technical cooperation, we aim to help customers shorten development cycles, reduce risks and keep a competitive cost-to-performance ratio in their markets.
