I have a new double injection mold, its weight is around 1 ton. I want to start making a budget for maintenance per year. Considering the total cost of the mold, Could you tell me, what percentage should I consider for its maintenance per year (preventive and corrective)?. Thank you in advance.

Dear Sir, Your first brush anti-embroidered paint. Costs will only occur for repairing the mold, placing and shipping.

about 5% of the total amount of the moulds,this is only for the repairing cost for the easy damaged parts.

Juan, The cost of maintenance and repair are very difficult to estimate. It depends on the complexity of the mold and the use it gets in operation. I normally put 5% per year of the total cost for very simple molds. Compex molds could go as high as 25% of cost of mold per year.

Juan,
This question is difficult to answer due to the many variables associated with a tool build. Giving a detailed answer would not be possible in this forum, but by keeping a tool maintenance log, and referring to historical data, you can fine tune your annual maintenance costs going forward.
Since the mold is newly acquired you have a couple of options that I would suggest. First, (and by far the easiest, but not necessarily the best), use a percentage of mold cost based on mold complexity. For example: 5% for a simple mold, 10% for more complex w/and side actions, etc.
The second suggestion, one that I personally believe gives you a more accurate picture of what one might expect from a new tool, is to have an experienced tool maker do a detailed inspection of the tool and make recommendations as to what your maintenance schedule should include along with suggested replacement intervals of pins, bushings, wear plates, etc. With your tool expert’s information in hand you should be better able to calculate what annual maintenance costs might include.
Another advantage of a detailed initial inspection is that it might also reveal existing tool issues, (even if new), that might not otherwise be exposed until your first production run. That initial inspection may also give you an idea of what mold components to stock so that mold downtime would be minimized should there be a tool issue with high wear components.
How or what you pass on to the customer is another discussion.
Hope this helps.

Juan, As previously mentioned, the cost of maintenance has a lot to do with the complexity of the tool and the hours of usage per day/week. You must evaluate how your tool performs with certain materials (Resins) as far as potential fouling occurs----such as vents clogging up. Tools that run 24/7 will typically require a "In Press" cleaning of the exposed mold surfaces and a weekly "Shop" teardown to fully clean, Inspect and lubricate the tool before being put back in service. Now for the cost involved.......based on your overhead costs for your personnel and time involved, you can estimate by hours the cost involved. After going through the maintenance process-----both for daily and weekly processes, you will understand the $$$$ spent. I would also suggest that if you have complex tools which have components that are prone to wear or possible fatigue failure during production, you establish a "Spare Parts" inventory to prevent extended downtime. Spare parts should be identified and bundled with the initial tool build------especially if your tooling is not built in house or locally.

Juan,

This is really a guessing game, We have no ides how complex, how many cavities, how many slides, how many lifters, how many nozzles or hot drops and what type, what material, how many parts per week....

You're best bet is a SWAG based on the data you've given us -----Scientific Wild Assed Guess

Thank you very much by your comments. All your comments have been very helpful for me. I really appreciate it.

Other potential issues consider (albeit may be minimal)

When you say "new double injection mold" I assume you are talking about a two material mold and injection press. Is it a multi-shot process or a co-injection process? If multi-shot, you may need to consider any costs for the maintenance of the mold rotation and/or robotic transfer and/or manual/ hand transfer.

We have been involved with very complicated rotate systems as well as some very simple rotate systems. Typically those that are custom, and more specific to the mold design, seem to have the highest potential for issues. Needless to say--there could be issues involved with wear, especially where moisture could possibly get into friction wear areas—if you have them.

Just realize that there may, or may not, be maintenance costs associated with how you are processing and transferring the product on top of all the other considerations brought up by others.
