How to do mold after-sales response and spare parts management

How to do mold after-sales response and spare parts management
The core of mold after-sales service is not commitment, but three things: spare parts list, response time, and remote support. If not done well, it can turn a shutdown into a one week shutdown.
The response time should be written into the contract
The common response time in the industry is 24-48 hours. Cross provincial projects typically require 48-72 hours for engineers to arrive on site.
The response time effect distinguishes between "remote response" and "on-site response". Writing only '24-hour response' without specifying the method has limited practical significance.
The downtime loss can be quantified. Stopping a line for a day often results in losses of tens of thousands of yuan, far exceeding the cost of a single on-site service.
The spare parts list should be provided at the time of delivery
The frequently replaced parts are concentrated in the top rod, exhaust plug, sealing ring, and locating pin. The list should clearly state the specifications, quantity, replacement cycle, and original supply channel.
The spare parts budget is generally calculated at 3% -5% of the mold purchase price, in exchange for not having to wait for the goods when a malfunction occurs.
Xinfeng Mold will hand over the spare parts list and drawings together with the wheel hub mold delivery to avoid re surveying due to unclear specifications in the later stage.
Which spare parts must be kept on hand
The highest proportion of downtime is caused by the breakage of the top rod. Thin rod inventory is taken as 1.5 times the actual monthly consumption, and thick rod inventory is taken as 1.2 times.
The exhaust plug blockage will not stop the machine, but it will affect the quality. It is recommended to keep a full round of usage and replace it directly after cleaning.
The sealing ring is an aging part and will harden after more than 2 years of inventory. Spare parts should be labeled with the date of entry and first in, first out.
How many problems can remote support solve
Parameter related issues can be resolved remotely. Abnormal mold temperature, pressure fluctuations, and dimensional drift can mostly be restored through parameter adjustment.
Structural issues can only determine direction remotely. Pulling, cracking, and popping noises usually require on-site treatment.
Suggest reserving data interfaces on the mold to transmit mold temperature and pressure data. The efficiency of remote diagnosis will be significantly improved.
How to arrange the maintenance plan
Sort by module, not by month. 5000 initial inspections, 10000 intermediate inspections, 20000 major inspections, and 30000 post encryption inspections.
The focus of the first inspection is on the top out and exhaust; Inspection and measurement of water flow rate and cavity size in the central inspection system; Perform stress relief and coating evaluation during the major inspection.
Maintenance records should be kept on file. Repeated failures in the same location indicate design or usage issues that cannot be easily resolved by replacement.
The risk of supplier replacement
If the mold drawings are not delivered and the supplier is changed, a new survey must be conducted. Surveying errors will directly affect the compatibility of spare parts.
The process parameters are not handed over, and new suppliers need to retest the mold, which usually takes 1-2 months.
Therefore, the delivery of drawings and parameters should be included in the contract at the time of initial procurement, rather than waiting until problems arise before discussing.
How to do shutdown and review
Record three things for each shutdown: duration of shutdown, direct cause, and root cause. The three are often inconsistent, and the fundamental reason is the object of improvement.
Calculate the distribution of downtime reasons for three consecutive months. The category that accounts for over 30% is worth undergoing special renovation instead of continuing to replace parts.
Frequently Asked Questions
Q: How long does the after-sales response usually take?
Answer: Remote 24 hours, on-site 48-72 hours.
Q: How many spare parts should be prepared?
Answer: Reserve inventory at 1.2-1.5 times the actual monthly consumption.
Q: How much does the spare parts account for in the mold price?
Answer: Usually 3% -5% is a necessary investment.
Q: What problems can be solved remotely?
Answer: Parameter related issues can be handled remotely, while structural related issues require on-site presence.
Q: Is maintenance based on time or frequency?
Answer: Conduct the first inspection after 5000 cycles.
Q: What should I pay attention to when changing suppliers?
Answer: The drawings and parameters must be obtained first, otherwise they need to be re surveyed.
