Is often thought of as the process somewhere in between sand castings and die casting.
Typically have higher piece price, but lower tooling costs.
Tooling can be very expensive initially, but the piece price is low.

Gravity Die-casting
Our Permold process is similar to pressure-die casting with the exception that our metal is gravity poured into a mold, as opposed to pressure Injected. This fundamental difference is why our castings are superior in so many different ways.

Denser Casting
Our unique die design system reduces metal turbulence dramatically and therefore virtually eliminates pinhole porosity commonly found in pressure-die casting. Moreover, even machined surfaces are pressure tight.

More Flexible Tooling
Our tooling is much easier and more inexpensive to change down the road when compared to Pressure-die casting. In fact, design changes to high-production dies can often cost as much as a brand New Permold tool.

No "Skin Effect"
Permold casting posses consistent mechanical and physical properties throughout the cross-section. Large bulky castings are actually our cup of tea.

Fully Machinable
Need a tight dimension that just can't be cast? No problem. Our castings are fully machinable. Also, Surfaces can be machined to mirror finishes.

Fully Weldable
Our castings are easily welded into assembly with excellent weld strength. Our castings are commonly welded with extruded aluminum tubing to make-strength structural units.

Shorter Lead-times
Shorter tooling lead-time makes your product to market faster. Shorter production lead-time reduces your excess inventory.

Short Cuts
Stop paying set-up charges and short-run fees. Get lot sizes as low as 250 pcs. without surcharge.

Better Ductility
Our Permold castings have better impact resistance and won't shatter. This is also known as "Louisville Slugger" resistant.

No Blistering or Distortion
Absolutely no casting blistering or distortion even at near melting temperatures.

No Burrs or Flash
All of our castings are hand-trimmed; never by trim press which inevitably leaves burrs and flash as it wears. Thus, our process is perfect for handles or other applications where hands-on contact requires safety.

Molded Inserts
Any metallic or ceramic piece can be cast-in. Saves costs over pressing inserts. Get stronger threads by casting threaded steel, brass, or stainless steel bushings and eliminate drilling and tapping. Reduce weight by casting a steel insert in high stress areas while keeping the bulk of material in lightweight Aluminum. Please consult SUPERKINO for more information on molded inserts.

Powder Coat Ready
Our castings easily take powder coating for a beautiful finish. Pressure-die casting often causes blistering of the powder coat during the heating cycle due to trapped gas.
