The core promise regarding maintenance parts supply centers on the question: “How long can parts still be purchased after equipment production ceases?” The EU’s “Right to Repair” directive, effective July 31, 2026, has transformed parts supply into a mandatory obligation.
A mature supply system comprises a four-tiered approach: “bundled spare parts kits,” “on-demand ordering,” “long-term supply agreements,” and “on-demand manufacturing.”
I.
Three Basic Supply Models
First, bundled spare parts kits: A kit of common wear parts (seals, fasteners, washers, etc.) is provided upon delivery of the main equipment to ensure proper installation and first-year maintenance. Second, on-demand ordering: Customers place orders using drawings or part numbers; the OEM or distributor ships from existing stock (common parts supplied locally; rare parts delivered via OEM channels within 5–15 days). Third, after-sales parts agreements: Key customers sign long-term agreements specifying pricing formulas, delivery commitments, and emergency channels (e.g., 24-hour emergency dispatch).

Supply Commitments After Production Ends: Industry Standards and Regulations
Industry benchmarks: Bosch Rexroth commits to supplying parts for 25 years after a product series is discontinued; Heli Forklift commits to 15 years from the date production stops; and mainstream domestic equipment manufacturers generally commit to supplying core components for 10 years.
Regulatory Perspective: The EU “Right to Repair” directive takes effect on July 31, 2026, mandating that manufacturers provide **spare parts for 7–10 years** (starting from when the last unit is placed on the market) at reasonable prices (preventing repair deterrence via excessive part costs), with delivery within 5–10 days and equal access to parts for independent repairers and authorized service networks. The EU Ecodesign draft further requires a minimum 5-year supply period after market withdrawal and delivery within 7 working days.
For hardware component suppliers, explicitly stating the “post-production spare parts availability period” and “delivery timeframe” in contracts ensures both regulatory compliance and a competitive edge.
III.
Channel and Inventory Strategy
First, **direct supply from the OEM**: Orders placed via official industrial e-commerce platforms with standardized part numbers (e.g., the Siemens Industrial Mall model), suitable for standard parts; second, **regional logistics centers**: Stocking at global or regional warehouses allows for urgent part delivery within hours to one day (e.g., the Bosch Rexroth model); third, **overseas warehouse stocking**: Storing frequently used parts in overseas warehouses within key markets for local dispatch; fourth, **regional agents/authorized repairers**: Handling local distribution and replacement services, with independent repairers enjoying equal rights to access parts as mandated by law.
A multi-point, multi-warehouse layout compresses delivery times from weeks to days.
IV.
On-Demand Manufacturing: 3D Printing Revives Discontinued Parts
Whether due to scrapped OEM molds, discontinued older models, or supplier bankruptcy, 3D printing (on-demand manufacturing) serves as a powerful solution for spare parts supply: **uploading CAD files or scanning old parts enables delivery in 2–5 days with no mold investment and no minimum order quantity (MOQ)**; metal parts utilize SLM or WAAM processes. A “digital inventory” model (storing CAD files rather than physical stock) can reduce lead times for critical spare parts by up to 92%.
This approach is particularly suitable for non-load-bearing hardware components, such as housings and brackets, whereas load-bearing structural parts must still be manufactured using original processes and certified materials.
V. Implementation Checklist
First, equipment delivery must include parts catalogs and interchangeability specifications (clearly marking parts shared across models); second, contracts must stipulate spare parts availability periods, lead times, and pricing formulas; third, establish a digital spare parts library (archiving CAD drawings for on-demand manufacturing); fourth, implement a dual-track supply strategy (OEM supply plus on-demand manufacturing backups);
and fifth, set up overseas warehouses for spare parts in key markets.
Industry experts note that the essence of spare parts supply is “giving customers the confidence to purchase your equipment”—by writing commitments regarding long-term availability and lead times into contracts and backing them up with a digital inventory for 3D printing, companies can significantly improve their reputation for after-sales support and boost repeat purchase rates for hardware components.
