Description
Insert injection molding for appliance parts
Insert molding is different from normal injection molding: before every shot, metal parts have to be loaded into the mold accurately, and the plastic must flow around them without moving them or leaving flash. The speed and accuracy of that loading step decide both the quality and the cost of the part.
This frame is molded in 30% glass-filled PA66 around metal inserts for a home appliance part.
Our approach to insert loading
Our engineering team and molding operators design custom loading tools that place a full set of inserts in one movement. This makes loading faster, more consistent and more precise, which:
- shortens the cycle,
- reduces scrap from misplaced inserts,
- lowers the part cost.
Tooling details
- Two cavities in AISI H13, cold runner, HASCO base.
- Insert locations with positive location features (pins, pockets or magnets) so inserts cannot shift as the mold closes.
- Tight shut-off around the inserts to prevent flash on threads and contact surfaces.
What is critical in insert molding?
The fit between insert and mold, the temperature of the insert (cold inserts can cause stress around them), and the consistency of loading. We control all three during the T1 trial and record them in the process sheet.

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

FAQ
What is critical in insert injection molding?
Accurate, repeatable insert placement, a tight fit between insert and mold to prevent flash, and controlling insert temperature so the plastic does not crack around cold metal.
Do you preheat metal inserts?
For larger inserts and glass-filled resins we often preheat them to reduce stress in the plastic around the insert.
Can insert loading be automated?
Yes, with robots and feeders at high volume. At moderate volume, a well-designed manual loading tool is usually the most economical.
