Import Auto Bumper Injection Mould Base — Buy in Bulk from Supplier in China

The Auto Bumper Injection Mould Base from Ningbo Fuxin Mould Base Co., Ltd. is a precision-engineered foundation component designed to support injection moulding tools for automotive bumper production.FT The base accommodates customer-specific 3D and 2D designs, allowing integration with varied bumper geometries across passenger vehicle and commercial vehicle programmes. Material specification centres on S50C or P20 tool steels, selected for their machinability, weldability, and dimensional stability under cyclic clamping loads. The mould base provides the structural framework into which cavity inserts, core inserts, and slide mechanisms are mounted, determining overall tool alignment and parting line integrity. Critical machined surfaces include the parting face flatness, guide pillar bore positional tolerances, and clamping plate parallelism.

S50C is a medium carbon steel equivalent to AISI 1050, offering tensile strength of approximately 690 MPa in the normalized condition and hardness of 170-230 HB. P20 is a pre-hardened chromium-molybdenum alloy tool steel delivered at 28-32 HRC, requiring no further heat treatment for most moulding applications and providing superior polishability for high-gloss bumper surfaces. The choice between these materials depends on production volume, surface finish requirements, and whether the bumper is painted or requires Class A show surface quality. Standard plate thickness tolerances for mould bases are plus or minus 0.02 mm per 100 mm of dimension, with parallelism of 0.02 mm or better over 300 mm length. Guide pillar to guide bush clearance typically ranges 0.01-0.02 mm for precision applications, with press-fit or bolted retention depending on cycle frequency.

Automotive OEMs and tier-one injection moulding suppliers represent the primary customer base for this product. Applications extend beyond standard bumpers to bumper fascias, lower valances, and integrated spoiler components where dimensional repeatability across million-cycle programmes is mandatory. The mould base must interface with specified machine clamp platens, requiring buyers to communicate tie bar spacing, clamp stroke, and ejection pattern at quotation stage. Ningbo Fuxin Mould Base Co., Ltd. operates from Tangxi Road in the Science and Technology zone of Ningbo, Zhejiang Province, a region with established supply chains for tooling and automotive components. Buyers should confirm the exact steel certification, heat treatment records, and dimensional inspection reports before finalising orders.

Ningbo Fuxin Mould Base Co., Ltd. is located at No.1, Tangxi Road, Science and Technology zone, Ningbo, Zhejiang Province, 315600, China. The supplier holds imported tier and harbor trust tier classifications. The response rate is recorded at 0.00 percent with zero average response hours, indicating no track record of platform-mediated communication. Buyers should establish direct contact through the provided address or alternative verified channels to evaluate responsiveness and technical support capability before committing to mould base procurement.

The company's location in Ningbo places it within one of China's most concentrated mould and die manufacturing regions, with established networks for tool steel distribution, CNC machining services, and surface treatment. The listing emphasizes customization based on customer 3D and 2D designs, suggesting a build-to-order rather than stock-based business model. No information is provided about years established, factory floor area, number of CNC machines, annual output, or client references. No certifications such as ISO 9001 or IATF 16949 are stated. Buyers are advised to request company registration documents, quality management system certificates, and evidence of previous automotive programme involvement.
