The after-sales maintenance cost of a flaskless molding machine is at the medium level among industrial foundry equipment. There is no absolute “high” or “low” conclusion, and the overall cost is directly determined by the equipment brand positioning and daily operation & maintenance habits. The long-term maintenance cost of equipment in different grades can differ by 3 to 5 times.
Maintenance cost differences for different grades of equipment
The overall purchase price is generally above 2 million RMB. The annual original factory maintenance fee usually accounts for 3%~5% of the original equipment value, with an annual cost of 60,000 to 100,000 RMB. The original spare parts for core hydraulic and electrical components have extremely high premiums, and the travel and labor costs for on-site services are added separately, leading to high long-term operation and maintenance costs.
The overall purchase price mostly ranges from 250,000 to 800,000 RMB. For brands that produce spare parts independently, the annual regular maintenance cost only accounts for 1%~2% of the original equipment value, with an annual expenditure of about 3,000 to 15,000 RMB. Most wearing parts can be replaced by the factory’s own operation and maintenance personnel after simple training, without paying high fees for original factory engineers to come on site. The long-term operation and maintenance cost is at a relatively low level in the industry, which is very friendly to small and medium-sized foundries.
The overall purchase price is only 10,000 to 50,000 RMB. Although the initial investment seems very low, the equipment has insufficient design redundancy and poor part universality, resulting in a much higher failure frequency than formal models. The hidden cost of sudden repairs in the later stage is even higher, and the long-term comprehensive maintenance cost is not cost-effective.
Core factors affecting maintenance costs
If the core spare parts of the equipment are independently produced by the brand and can be quickly purchased locally, the price of the spare parts is only 1/3 to 1/2 of that of imported general parts, which can greatly reduce the long-term operation and maintenance expenditure. If you rely on imported exclusive customized spare parts, not only the supply cycle is as long as 1 to 3 months, but also the price of spare parts is several times higher.
For models with modular design, daily inspection and replacement of wearing parts do not require disassembling the whole machine. The factory’s own electricians and mechanics can complete the work independently, eliminating the high labor cost of original factory on-site services. For models with compact design and narrow maintenance space, every small fault requires professional engineers to be present, and the proportion of labor costs will greatly increase the total maintenance expenditure.
For equipment that strictly replaces hydraulic oil, cleans accumulated sand in the sand shooting chamber, and tightens seals regularly according to the manual, the annual sudden failure maintenance cost can be controlled within 2,000 RMB. If the equipment runs with faults for a long time without preventive maintenance, the cost of a single major overhaul of the hydraulic system or main oil cylinder may exceed 20,000 RMB.
Practical tips to control maintenance costs
- ✔ At the procurement stage, confirm the supplier’s standing inventory list of wearing parts in advance, and require them to provide a public quotation list of spare parts to avoid being tied up by high-priced “exclusive spare parts” in the later stage.
- ✔ When the equipment is accepted and put into production, require the manufacturer to complete the full-process operation training for the factory’s own operation and maintenance personnel, so that they can master the ability to independently replace wearing parts and troubleshoot common small faults, reducing the dependence on external after-sales services.
- ✔ Sign an annual preventive maintenance agreement to lock in the annual regular on-site inspection service with a fixed annual fee. Compared with calling for repair temporarily after a fault occurs, the overall expenditure can be reduced by more than 40%.
