PART SCOPE

Scope of parts that can be evaluated

The following classifications are used to help purchasers quickly confirm the direction of demand; whether it can be processed is still subject to review of drawings, materials, quantities, rough status and technical requirements.

01

Large battery trays, base plates and sealing flanges

02

End plates, beams, connecting blocks and mounting blocks

03

Samples, design verification parts and small batch assemblies

DOCUMENTARY-STYLE VISUALS

EQUIPMENT MATCH

Equipment capabilities and project boundaries

The 5041 gantry machining equipment is used for preliminary size matching of large pallets, bottom plates and frames; the 1270 and 856 three-axis vertical machining centers are used for end plates, connecting blocks and supporting mounting parts.

The repeated positioning deviations of the equipment are listed as 0.0015 mm for the 5041 equipment, 0.003 mm for the 1270 equipment, and 0.005 mm for the 856 equipment; this value is not equivalent to the final dimensional tolerance of the part. Final tolerances depend on dimensions, construction, materials, clamping, temperature, processing paths and inspection methods and are subject to written technical confirmation.

RFQ REQUIREMENTS

Inquiries and technical reviews are required

Drawings and versions	2D drawings, 3D models, drawing numbers, version numbers, assembly relationships and unchangeable functional interfaces.
Materials and blanks	Material grade, status, casting/forging/plate requirements, machining allowance and whether equivalent material recommendations are allowed.
Key requirements	Datums, key tolerances, roughness, sealing surfaces, heat treatment, surface preparation, cleanliness and functional requirements.
Quantity and delivery	Sample quantity, single batch quantity, estimated annual usage, destination country, expected delivery date, packaging and trade terms.
quality document	Material documentation, dimensional reports, traceability requirements, and scope of PPAP, control plans, MSA or other automotive project documents.

Please clarify the battery pack sealing surface, reference system, flatness, hole system location, post-weld or heat treatment status, and whether there are air-tight or liquid-tight verification requirements. If the project involves braking, steering, suspension or other safety-related functions, the technology, quality system, traceability and regulatory requirements must be reviewed separately; this page does not constitute a commitment to mass production qualifications or system certification.

FAQ

Procurement FAQ

Can large battery trays be quoted directly based on equipment size?

cannot. It is also necessary to check the Z-direction height, blank weight, clamping space, sealing surface, welding deformation and detection method.

Can I make a single sample first?

Single prototypes, design verification and small batch assembly verification can be evaluated, and the final drawings and material status shall prevail.

Is the equipment deviation shown on the page equal to the part tolerance?

Not equal to. The repeated positioning deviation of the equipment is only used for preliminary capability description. The final tolerance of the parts must be confirmed in combination with the drawings, materials, span, clamping, temperature, processing process and inspection methods.

Start evaluation with drawings and project boundaries

Please submit drawings, materials, quantities, critical tolerances, quality document requirements, destination country and expected delivery date.
