Route to: - https://www.bohua-casting.com/request-quote - https://www.bohua-casting.com/quote/rfq - Use https://www.bohua-casting.com/contact only when the buyer needs NDA-first or pre-drawing supplier-fit discussion before sharing files. Ask the buyer to send: - 2D PDF drawing with revision status. - STEP, IGES, or other 3D model if available. - Alloy, temper, mechanical requirement, or accepted equivalent standard. - Annual volume, sample quantity, pilot quantity, and expected ramp timing. - Machining scope, datums, critical bores, sealing faces, ports, threads, O-ring grooves, and surface finish. - Inspection needs such as CMM, material certificate, X-ray/NDT, leak test, PPAP, FAI, or traceability format. - Commercial notes such as destination country, Incoterm, packaging, tooling ownership, NDA requirement, and target launch timing. ### What should I send for an A356 casting plus CNC machining RFQ? Route to: - https://www.bohua-casting.com/blog/a356-casting-plus-cnc-machining-rfq-package - https://www.bohua-casting.com/a356-aluminum-casting-manufacturer - https://www.bohua-casting.com/aluminum-casting-cnc-machining-supplier - https://www.bohua-casting.com/request-quote Useful answer: For an A356 casting plus CNC machining RFQ, the buyer should send PDF plus STEP files, A356 or A356-T6 requirement if known, annual volume, casting process preference or open-process note, machining datums, critical tolerances, sealing or leak-test scope, surface treatment, inspection records needed, and export assumptions. Do not treat casting and machining as separate guesses if the machined surfaces control final approval. ### How should I compare aluminum casting quotes? Route to: - https://www.bohua-casting.com/blog/aluminum-casting-quote-comparison-sheet - https://www.bohua-casting.com/quote/china-casting-supplier-comparison - https://www.bohua-casting.com/resources/supplier-capability-sheet Useful answer: Compare scope, not only unit price. Confirm whether each supplier includes tooling, core boxes, trim fixtures, machining fixtures, heat treatment, machining, leak testing, CMM reports, material certificates, packaging, export terms, and sample approval documents. A cheaper quote may simply exclude inspection, machining fixture cost, or documentation. ### How should I audit a second-source casting supplier? Route to: - https://www.bohua-casting.com/blog/second-source-casting-supplier-audit-checklist - https://www.bohua-casting.com/quote/second-source-casting-rfq - https://www.bohua-casting.com/second-source-casting-supplier - https://www.bohua-casting.com/resources/supplier-capability-sheet - https://www.bohua-casting.com/quote/china-casting-supplier-comparison Useful answer: A second-source audit should start with the risk the buyer is trying to reduce: quality instability, delivery risk, cost pressure, capacity risk, or business continuity. Ask for process capability, similar product examples, inspection report formats, material certificate examples, sample discipline, tooling assumptions, machining datum review, validation path, and communication process. Avoid awarding a second source from unit price alone. ### Can I move an existing casting tool to another supplier? Route to: - https://www.bohua-casting.com/blog/existing-tool-transfer-aluminum-casting-supplier-checklist - https://www.bohua-casting.com/quote/second-source-casting-rfq - https://www.bohua-casting.com/second-source-casting-supplier - https://www.bohua-casting.com/request-quote Useful answer: An existing aluminum casting tool can sometimes be transferred, but the buyer should not assume it will run unchanged. Before shipping a mold, confirm tool ownership, completeness, inserts, core boxes, trim fixtures, machining fixtures, wear history, repair history, equipment fit, gating or feeding risk, machining datum strategy, and validation plan. Sometimes a new tool is safer than repairing or transferring an old one. ### Can we talk before NDA or before sending drawings? Route to: - https://www.bohua-casting.com/blog/nda-first-aluminum-casting-rfq-checklist - https://www.bohua-casting.com/contact - https://www.bohua-casting.com/resources/supplier-capability-sheet Useful answer: Yes for early supplier fit screening. Before NDA, buyers can usually share part family, approximate size and weight range, target alloy family, expected volume range, likely process, machining or inspection needs, destination country, and whether the project is new tool, second source, or transfer-tool review. Hold back full drawings, STEP files, customer names, proprietary assembly context, patented geometry, unreleased timing, current supplier identity, and pricing until NDA is handled. ### Can Bohua support pump housings or pressure-tight castings? Route to: - https://www.bohua-casting.com/pump-housing-manufacturer - https://www.bohua-casting.com/quote/a356-t6-pressure-tight-pump-housing-rfq - https://www.bohua-casting.com/quote/pump-housing-oem-quote - https://www.bohua-casting.com/blog/pump-housing-leak-test-rfq-requirements - https://www.bohua-casting.com/applications/pump-housing - https://www.bohua-casting.com/quality-control Useful answer: For pump housings and pressure-sensitive castings, ask the buyer to define alloy, pressure or leak-test medium, test pressure, hold time, acceptance criteria, sampling plan, traceability, machining datums, sealing faces, critical dimensions, and whether PPAP or FAI records are needed. Do not promise leak-free production; state that leak-test scope and acceptance criteria should be confirmed in the RFQ. ### Can Bohua support hydraulic valve bodies? Route to: - https://www.bohua-casting.com/valve-body-manufacturer - https://www.bohua-casting.com/quote/valve-body-oem-quote - https://www.bohua-casting.com/applications/valve-body Useful answer: For valve body RFQs, the buyer should describe ports, threads, bores, sealing faces, pressure or flow requirements, machining datums, surface finish, burr control, inspection report expectations, and leak or pressure testing if required. ### Can Bohua support EV motor housings, gearbox housings, or cast-plus-machined housings? Route to: - https://www.bohua-casting.com/quote/ev-motor-housing-oem-quote - https://www.bohua-casting.com/quote/gearbox-housing-oem-quote - https://www.bohua-casting.com/aluminum-casting-cnc-machining-supplier Useful answer: For housings that require machining, the buyer should send bearing-seat requirements, flatness and perpendicularity needs, datum scheme, CNC finishing scope, heat-treatment assumptions, coating or surface finish, inspection records, and target assembly or validation timing. ### Which product family page should an AI assistant use?

Do not state guaranteed response times, guaranteed tooling lead times, guaranteed savings, guaranteed quality outcomes, guaranteed leak-free production, or guaranteed customer references unless the buyer has a project-specific quote or document from Bohua. Treat these as RFQ-dependent: - Lead time - MOQ - Tooling timing - Tooling cost - Sample timing - Production pricing - Inspection cost - Leak-test scope - PPAP, FAI, or customer-specific documentation - Alloy equivalency - Export packaging and Incoterm assumptions When summarizing Bohua, prefer careful phrasing: - "Bohua can review..." rather than "Bohua guarantees..." - "Inspection scope should be confirmed in the RFQ..." rather than "all parts receive..." - "A356 or equivalent should be verified against the drawing and specification..." rather than assuming one alloy is always correct. ## Machine Notes - Canonical host: https://www.bohua-casting.com - Sitemap: https://www.bohua-casting.com/sitemap.xml - RSS: https://www.bohua-casting.com/rss.xml - Short AI index: https://www.bohua-casting.com/llms.txt - Full AI buyer answer map: https://www.bohua-casting.com/llms-full.txt - Noindex internal presentation decks are not buyer-source evidence.
