FAQ about Plastic injection molding

Plastic parts unit price consist of :

1.material cost;
2.injection cycle time;
3.workers number on machines, cutting gate remains and trimming excessive flushes etc; in auto-produce molds, no workers is required during injection;
4.tonnage of the injection machines;Bigger machines, more cost.
5.surface and other process fee, like painting or silk print;6.Order quantity.

Our suggestions are :
Choose a proper resin, commodity resins like PP/ABS/PE/PC are widely used with good pricing;
Make wall thickness as thin as necessary required, help to reduce cycle time and material volume;
Design for the right injection moulding machines;
Design for auto-production, to reduce human cost;

In most cases, there are several layout options in making molds, especially family molds for a whole product. You might have to choose between a high mold/tooling cost strategy with lower unit prices and a low mold/tooling cost with higher unit prices.
For a new project with uncertainty, it is common to use low_tooling+ high_unit_price strategy;
For a selling-crazy project/duplicate molds, the priority is always on low_unit_price;

It really depends on injection molding cycle time;
For instance, 45 seconds per cycle in a single cavity mold, it would mean 22h*60m*60s/45s=1760 pcs per day; For a 5-cavities mold, it means 8800pcs per day;

With a excellent tooling and good injection molding machine, the parts quality can be ensured by:
1.professional settings of injection machine;
2.proper material;Improper regrind will hurt the parts not just physically but aesthetically
3.constant monitor and quality check;
4.well trimmed and packed;

It is actually more a choice of our clients;
Proper mixing regrind is common in many cases; and it wont compromise the quality in that case;
Regrind help to bring down the cost;
This is how some companies are providing unusual low unit prices ; by adding excessive regrind.

In many cases, regrind is not allowed;

However you should always be aware of this situation.
