PC ABS Automotive Part Mould With SKD61 Cavity Steel
Single cavity PC/ABS tool, SKD61 cavity, four slides, submarine gate, 60 sec cycle, 600,000 shots.
What This Tool Is
An interior part tool in SKD61, chosen because PC ABS runs hotter and more abrasive than plain ABS and will wear a pre-hardened cavity at the gate. The tool runs four slides and a submarine gate. The archived record puts the cycle at 60 sec and the tool life at 600,000 shots.
PC ABS sits between the two: stiffer and hotter than ABS, easier to fill than straight PC, and abrasive enough that cavity steel choice starts to matter.

Key Benefits
SKD61 is a hot work tool steel, which is why it is the cavity steel on this a PC ABS automotive interior part tool
A submarine gate runs under the parting line and shears off during ejection, so the part leaves the press finished
A single impression keeps the tool cost down and makes sense until annual volume genuinely outgrows one cavity
Four slides let the part keep features on faces that a simpler tool would have forced the designer to delete
PC ABS sits between the two: stiffer and hotter than ABS, easier to fill than straight PC, and abrasive enough that cavity steel choice starts to matter
Problems It Solves
A tool laid out around ABS cooling will not hold cycle or finish once a polycarbonate grade goes into it
Hand degating a cosmetic part risks damaging the very face it is being trimmed on
A single impression tool cannot supply a programme once it reaches production volume, and by then the tool is already paid for
Who It Is For And Where It Is Used
Who it is for
- Tier two automotive suppliers
- Interior trim manufacturers
- Programme buyers second sourcing an existing tool
Application scenarios
- Adding an interior bracket inside a model year
- Second sourcing a tray table tool and matching the incumbent parts
- Replacing a worn door panel tool without changing the assembly fixture
Technical Features And Materials
Technical features
- SKD61 cavity and core
- 1 x 1 impression layout
- Submarine gate feed
- Four mechanical slides with hardened wear plates
- Cavity and core rated at 600,000 shots
- HASCO or DME standard mould base components
Customisation options
- Built as a two cavity or multi impression tool where the annual volume supports it
- Cavity steel changed from SKD61 where your moulding grade or your expected shot count calls for something different
- Gate type moved away from the submarine gate if the cosmetic face or the degating requirement changes
- Cosmetic features such as texture, logos and part numbers cut as replaceable inserts so a later change does not mean a new cavity
- Mould base built to HASCO or DME dimensions, or to a standard your own tool room already stocks spares for
Materials
- PC/ABS
How This Mould Is Made
- Cavity and core blocks are inspected against the specified grade before they enter the machining route
- Cavity geometry is cut on the CNC machining centres from programmes generated off the released part model
- Rib roots, text and internal corners are burned in with EDM electrodes, which is detail no rotating cutter can reach
- The four slide pockets are wire cut so the slide fit repeats rather than being filed in
- The moulding face is polished to the finish the part needs, which for a plated part is a different grade from a textured one
- Parting line, shut offs and ejection are fitted and spotted by hand at the bench
- The tool is trialled on one of our injection machines and the 60 sec cycle is measured rather than assumed
Quality Control On This Tool
- Incoming cavity and core steel is checked against the grade on the order, not against the delivery note
- Machined inserts and plates are measured between operations rather than only at the end of the route
- Slide travel and shut off contact are checked at the bench before the tool goes anywhere near a press
- Trial parts are measured on the 2D image measuring projector against the dimensions nominated on your drawing
- Corrections found at trial are recorded against the mould number with the date and the reason, so a repair years later starts from what the tool actually is
- Before shipment the water and hydraulic circuits are blown out and plugged and the moulding faces are oiled
Compared With The Alternatives
A two cavity version of the same part
Doubles output per cycle for roughly 60 to 70 percent more tool cost. It pays back above a few hundred thousand pieces a year and not below.
A pre-hardened P20 or 718 tool
Cheaper and faster to cut, but it will not hold this tool's finish for this tool's shot count in this material.
A hot runner version
Removes the runner weight and allows a gate in the middle of the part, at a higher tool cost and with a heated manifold to maintain.
Use And Maintenance Guide
- Run the tool in the PC/ABS grade it was trialled with; changing grade changes shrinkage and cavity wear at the same time
- Inspect the submarine gate at every service, because gate condition is what decides whether parts come off the tool clean
- Grease the slide gibs on the interval in the tool documentation rather than waiting for flash to appear
- Check that every slide returns fully after a press change; a slide that does not return will damage the cavity on the next close
- Oil the moulding faces and plug the circuits for any storage longer than a week

PC ABS Automotive Part Mould With SKD61 Cavity Steel Questions
What buyers ask about this tool before ordering.
Why SKD61 for this tool?
SKD61 is a hot work tool steel. It holds up to the melt temperature of PC and PC blends and resists the abrasion that filled and flame retardant grades cause at the gate, where a pre-hardened cavity wears first.
What does the submarine gate mean for the finished part?
A submarine gate runs under the parting line and shears off during ejection, so the part leaves the press finished. It needs a non cosmetic face to sit on and room beneath the parting line.
What does the 600,000 shots figure actually cover?
It is the cavity and core life the tool was built for, running the nominated PC/ABS grade under normal maintenance. It is not a guarantee against damage from a mispositioned part, a press fault or a missed service interval.
Is the 60 sec cycle achievable in our press?
It was measured on a trial here with the mould running PC/ABS. Cycle time follows the heaviest section of the part far more than it follows the press, so it should transfer, but confirm your clamp tonnage and cooling capacity with us first.
Do you supply the moulded parts as well as the mould?
Yes. The plant runs injection machines below 600 tons on the same site as the tool room, so a mould built here can be trialled and then run for production without shipping it anywhere.
