Product Overview
Gear Box 4 is designed for industrial equipment assemblies that require stable geometry, dependable fastening surfaces, and repeatable fit-up in production.
A356-T6 is a practical alloy choice for this part because it offers good strength, corrosion resistance, and heat-treat response, making it suitable for structural castings and flow components.
Gravity Casting gives this component good dimensional stability, dense section quality, and a clean casting surface that supports follow-up machining on sealing faces, ports, or mounting points.
This variant is typically supplied for industrial equipment and transmission equipment programs, with geometry tailored to OEM drawings, tooling requirements, and downstream assembly needs.
Material
A356-T6
Reviewed against drawing function, casting route, machining stock, corrosion expectations, and the buyer approval scope.
Manufacturing Process
Gravity Casting
The process plan should define mold route, pouring assumptions, post-casting machining, inspection points, and any sealing-surface requirements before quotation.

What to send when quoting this part
Drawing package
2D PDF plus STEP/IGES if available; mark critical datums, sealing faces, ports, bores, threads, and assembly surfaces.
Volume and timing
Prototype quantity, first order quantity, annual demand range, target sample timing, and repeat-order schedule.
Material and process
Current page reference is A356-T6 with Gravity Casting; note accepted alternatives if your engineering team allows them.
Machining and inspection
CNC scope, CMM report needs, material certificate, leak test, PPAP, FAI, traceability, coating, packaging, and export destination.
Follow-up channel
Submit the site RFQ first; note NDA-first review needs and use email or WhatsApp only as fallback for failed delivery or manual drawing attachments.

Product RFQ FAQ
Questions buyers ask before quoting Gear Box 4
Use these notes to prepare a drawing-based RFQ. Final pricing, tooling, sample timing, machining, and inspection scope depend on the actual drawing package and commercial requirements.
What should buyers send to quote Gear Box 4?
Send a 2D PDF drawing, STEP or IGES model if available, target alloy or accepted equivalent, annual volume, sample quantity, machining scope, inspection requirements, destination country, and target timing. For Gear Box 4, also note critical datums, sealing faces, ports, threads, or assembly surfaces if they affect final approval.
Which material and casting process are listed for Gear Box 4?
This representative page lists A356-T6 and Gravity Casting. Final material, temper, casting process, machining allowance, and inspection scope should be confirmed from the drawing, wall thickness, tolerance stack, functional requirement, and annual demand during RFQ review.
Can Bohua review machining and inspection requirements for Gear Box 4?
Yes. Buyers should mark CNC datums, bores, sealing faces, thread requirements, surface finish, CMM report needs, material certificate needs, leak-test scope, PPAP, FAI, or traceability requirements in the RFQ. Bohua reviews the casting and post-casting scope together instead of quoting only the raw casting shape.
Is Gear Box 4 a standard stock item?
Bohua product pages show representative custom aluminum casting work. Most OEM projects are quoted from buyer drawings rather than sold as stock catalog parts. Send the drawing package and sourcing context for project-specific feasibility, tooling, sample, machining, inspection, and export review.
