Wenlio Machining Service
Broaching
Extensive inventory of broaches in various sizes and shapes, making us the ideal choice for urgent order.
Grinding
These services include ID/OD, gear or spline, thread, jig or surface grinding.
Hobbing
With over 10,000 hobs in stock, we likely already have the tooling available for your custom order.
EDM -Wire and Ram
Especially well suited for operations requiring high accuarracy and low-count quick-turnaround part runs.
Laser cutting
Producing for small batches, thin-plate gears (typically <20mm), non-standard gears.
Shaping
Shaping capacities range from 0 to 40″ diameter, and pitches from 1 to 1000.
Shaving
Constructed with a heavy-duty frame for stability and often features automated loading systems.
milling
4th axis capabilities, hold tolerances within .0002″ linear and 10 arc second rotary repeatability.
Quality Control
Prior to every shipment, we conduct the following tests and provide complete quality reports for these gears.:
1. Bubble drawing
2. Dimension measurement report
3. Material certification report
4. Heat treatment testing report
5. Accuracy measurement report

Packaging
Step 1 – Anti-rust: We wrap each gear with VCI anti-corrosion paper / bag to protect it from rust during shipping.
Step 2 – Inner protection: The wrapped parts are placed properly to avoid scratches and impact.
Step 3 – Carton packing: Then we pack them into strong export cartons (logo printing is available).
Step 4 – Crate & pallet: Cartons are loaded into a reinforced plywood crate with partitions, and fixed on a pallet.
Step 5 – Secure & label: The crate is sealed, strapped, and labeled, ready for sea/air shipment.
We can also provide custom printed color boxes and logo customization (carton, color box, crate marking, labels).
Note: Please ensure the logo/design is authorized by you; if it involves any third-party brand, we will need written authorization to avoid IP risks.
FAQ
Do you supply metal helical gears for forklift gearboxes?
Yes. We supply helical gears for forklift gearbox stages where stable engagement and load sharing are important. Send your ratio, speed, and torque so we can recommend material and heat treatment consistent with real duty conditions.
Can you supply one gear or a complete helical gear set?
Both are possible. For gearbox projects, providing mating gear details helps reduce fit risk and unexpected noise. If you can share the mating part or its drawing, we can check interface and recommend a safer manufacturing route.
What RFQ details are required for a forklift helical gear?
Provide module/DP, tooth count, helix angle, face width, bore/spline details, material, heat treatment target, speed, torque, and quantity. Mention duty cycle and shock loads because forklifts often see frequent starts, stops, and reversals.
How do you control smooth running for helical gears?
Smoothness mainly depends on tooth geometry control, runout, and surface finish. If you share your backlash target and speed range, we can suggest practical tolerances and inspection points rather than guessing, which helps prevent rework after assembly.
What inspection evidence can you provide for incoming QC or PPAP-style needs?
We can provide dimensional and tooth measurement evidence, hardness checks, and other records as requested. Share your documentation list early so we can plan the inspection package correctly.
What are common causes of forklift gearbox gear failures?
Misalignment, lubrication breakdown, contamination, and overload are common. The housing and bearing support can shift under load, changing contact. Share your layout and oil details so we can recommend realistic backlash targets and finishing requirements.
