• Before Quotation

Not Every Gear Inquiry Can Be Quoted from Photos Alone

Many buyers send a tooth count, outside diameter, or several product photos. For custom gear manufacturing, that is often not enough. Gear type, material, heat treatment, mating gear data, accuracy requirements, and application conditions may all affect quotation and production feasibility.

Practical advice: If you do not have a complete drawing, send clear photos from multiple angles, sample dimensions, application information, quantity, and any OEM number or mating gear details.

Incomplete Gear Data

A photo may not confirm module, pressure angle, tooth geometry, bore details, spline, or mounting dimensions.

Mating Gear Influence

For bevel gears and paired gears, backlash, tooth contact, and installation results depend on the mating part.

Worn Sample Risk

Worn teeth, damaged bores, or deformed keyways should not be copied directly without technical review.

Quotation Delays

Missing material, heat treatment, quantity, or application details usually causes repeated communication.

• Manufacturing & Inspection

Process-Driven Manufacturing Capabilities

For custom gear projects, the manufacturing route should match the gear type, material, heat treatment, accuracy, quantity, and application requirements.

Gear Blank & Machining

Forging, turning, hobbing, shaping, milling, and machining routes can be reviewed according to project requirements.

Gear Inspection

Profile, lead, pitch, runout, hardness, and key dimensions can be checked according to drawing and agreed requirements.

Heat Treatment Planning

Carburizing, nitriding, induction hardening, or through-hardening can be discussed based on load and wear requirements.

Documentation

Material certificates, hardness reports, dimensional reports, and gear inspection data can be prepared when required.

Precision Finishing

Grinding, lapping or finish machining may be considered when accuracy, tooth contact or assembly requirements demand.

Packaging Support

Anti-rust treatment, individual protection, export packaging, and logistics coordination can be arranged by order needs.

• Project Workflow

Your Custom Gear Project: From Inquiry to Delivery

A clear workflow helps buyers know what happens after submitting drawings, samples, or technical details.

Step 01

Drawing or Sample Review

We check whether the current information is enough for quotation or whether more details are needed.

Step 02

Technical Clarification

Gear type, material, heat treatment, accuracy, quantity, application, and mating conditions are clarified.

Step 03

Quotation & Process Plan

Quotation is prepared based on manufacturability, process route, inspection requirements, and project quantity.

Step 04

Prototype or First Article

For new or replacement projects, sample confirmation may be needed before batch production.

Step 05

Inspection & Review

Key dimensions, hardness, gear accuracy, tooth contact, and related documentation are reviewed as agreed.

Step 06

Production & Delivery

After approval, the project moves to production, packaging, and shipment according to the confirmed plan.

• Application Fit

Gears for Demanding Transmission Applications

Wenlio’s custom gear review is best suited for B2B industrial applications where drawings, samples, and working conditions matter.

Agricultural Machinery

Tractor, harvester, gearbox, and field equipment transmission parts.

Heavy-Duty Trucks

Transmission gears, axle gears, differential-related parts, and replacement gear projects.

Construction Equipment

Loader, excavator, forklift, final drive, and high-load machinery applications.

Electric Vehicles

Reduction gears, transmission components, and e-axle related gear projects.

• Quality Review

Inspection Is More Than a Final Check

For custom gear projects, quality review should begin before production. Material selection, heat treatment, machining process, tooth contact, and measurement requirements all affect the final result.

Dimension check: OD, ID, face width, bore, spline, keyway, and mounting dimensions.
Gear geometry: tooth profile, lead, pitch, runout, and related drawing requirements.
Material properties: surface hardness, core hardness, and case depth when required.
Documentation: inspection reports and supporting records can be prepared according to order needs.

• FAQ

Common Questions Before Sending a Custom Gear RFQ

Can Wenlio quote if I only have a sample or photos?

Yes, we can review sample-based projects, but photos alone may not be enough for final production. If the old part is worn or damaged, additional measurement, drawing confirmation, or mating gear information may be needed.

What information should I send for a faster quote?

Please send drawings, sample photos, gear type, material, heat treatment, quantity, application, and mating gear information if available. The more complete the information is, the faster the review can move forward.

Can you support prototype or small batch custom gears?

Some projects can start with prototype or small batch production, depending on gear type, material, tooling, heat treatment, and inspection requirements.

Why is mating gear information important for bevel gears?

Bevel gear performance depends on the gear pair, not only one part. Mating gear data may affect backlash, tooth contact, installation, noise, and load distribution.

What inspection reports can be provided?

Depending on the order requirements, material certificates, hardness reports, dimensional reports, and gear inspection data can be provided for review.
