OK, we've got your Mould Tool and Raw Material, now we've got to make your MOULDED PARTS.
We put your tool into one of our Injection Moulding Machines, fill the hopper with raw material and press the start button. (if only it were so simple)! The cycle time of the machine is determined by the part design. Thin part sections cool faster than thick and therefore can be cycled faster. As a rough guide, a part with a 1mm wall section might cycle at about 10 seconds and 3mm at around 30 seconds.
So, how much does this bit of the moulded part cost? Most moulders will have an hourly rate based on the size of the moulding machine been utilised for your job, so if running a 2 cavity tool at 20 seconds (360 parts per hour), the part cost is Hourly Rate/360.
There may be after operations such as assembly or printing and these costs are calculated separately and added to the piece price.
There will also be packaging and delivery costs and of course, big parts use more packaging and usually cost more to transport.
