3ERP
Company-source research for CNC-machined aluminum prototypes and production parts, with a published head-office and factory location in Zhongshan, Guangdong.
Source-described identity and services
- Name presented on source
- The company overview presents 3E Rapid Prototyping (3ERP). This is a source-described name, not independent company-registration evidence. Ask which exact legal entity will quote, contract and invoice the proposed order.
- Published aluminum service scope
- The CNC service page lists aluminum among machining materials and describes milling and turning. This record covers CNC-machined aluminum parts only; the website separately lists other manufacturing services.
- Source-reported contact location
- The contact page labels No. 5–7 XingGang Avenue South, GangKou Town, Zhongshan, Guangdong, as Head Office & Factory 1. It separately lists a USA office. Confirm the actual operations and dispatch site for your order rather than assuming the contact address covers every step.
Questions before requesting a part quotation
- Drawing and quotation control
- Identify part number, drawing revision, CAD revision, units, quantity and required delivered condition. Agree which document controls acceptance. Record supplier-proposed changes as exceptions for review.
- Starting stock and material evidence
- State the required alloy and temper instead of choosing solely from a website list. Ask how the starting stock, material identification and relevant records will be linked to the finished parts and shipment.
- In-house and partner operations
- The homepage describes both in-house work and manufacturing partners. Ask which site performs machining, finishing, inspection and packing, and which entity remains responsible for outsourced steps.
- Inspection after finishing
- Define critical features, datum interpretation, report requirements and acceptance ownership. Ask whether inspection applies to the final delivered condition after coating or other secondary work, and how samples and reports reference the drawing revision.
- Trial versus repeat production
- Separate prototype parts, fixtures, setup, sample approval and repeat orders. Request confirmation of any change in stock, machine route, fixture, finishing supplier or inspection method between the trial and subsequent batches.
- Complete commercial scope
- Compare raw material, secondary work, inspection, surface protection, packing, transport terms and release conditions together. Obtain written exclusions and an order-specific lead-time response; general website timing and tolerance headlines are not a quotation.
Record status and evidence limits
This is an editorial research record based on company-published sources, not a supplier-submitted listing, paid placement or independent factory audit.
The official homepage describes manufacturing through in-house facilities and partners. This record does not independently audit those sites or establish certification validity, customer relationships, alloy stock, application qualification, tolerance capability, minimum order, price or delivery timing. Only CNC-machined aluminum parts are tagged in this directory.
Source review: 3 October 2026. Prepare a correction if a field or source changes.
