Description
What a family mold is
A family mold contains cavities for different parts of the same product, molded together in one shot. For small electronic devices this usually means the top and bottom of a housing, or a housing and its cover. Our 1+1 family mold molds two different ABS parts per shot.
For small-volume and short-run molding, a family mold reduces both the mold cost and the molding cost, while still producing parts that meet the quality standard.
The challenge: different parts, one shot
The two parts can differ a lot in size, weight and wall thickness. In one shot, the melt must fill both completely without overpacking the smaller one. Handling filling and cooling for different sizes is where experience counts:
- Runner and gate sizes adjusted so both cavities finish filling at the same moment.
- Shut-off valves or runner inserts where needed to run one cavity alone.
- Cooling tuned to each part's wall thickness.
Tooling details
Single 1+1 layout in AISI H13, cold runner, HASCO standard. Parts with similar weight, colour, material and surface finish are grouped together, following our injection machine sizes, to keep the mold as small as possible.

How we work
How a project like this works
- Tell us what you need – the mold only, molded parts, or both, and your estimated annual volume.
- Send drawings – STEP, IGES, STL, DWG or PDF, or a sample. We sign off moldability in a DFM review.
- Quotation – tooling price, part price and a schedule, with steel, cavities and runner proposed.
- Mold design approval – you approve the 3D mold design before steel is cut.
- T1 samples + FAI report – production or mold shipment starts after your approval.
Shipping molds and parts
- Molds are cleaned, rust-protected, marked and checked against a shipment checklist: cooling circuits, sprue, locating ring, ejection and support pillars.
- Molds ship with drawings, a spare-parts list and the T1 process sheet.
- Parts are packed to your packing instruction and inspected before shipment.
- We ship to customers in Europe, the USA and Asia.
After-sales
Our after-sales team supports mold maintenance and modifications remotely and can supply spare inserts. Contact customerservice@precisemoulds.com.
FAQ
When is a family mold a good idea?
When the parts are used in equal quantities, share the same material and colour, and volumes are low to moderate. For high volumes, separate molds usually give better control.
Can one cavity of a family mold be run alone?
Yes, if the mold has runner shut-offs or blocking inserts. This is useful when one part needs replacing more often.
Do family molds compromise quality?
Not when the runner is balanced and the parts are grouped sensibly. Large differences in size or wall thickness make it harder, which we assess during DFM.
