*Permanent Mold   : Is often thought of as the process somewhere in between sand castings and die casting.
*Sand Casting   : Typically have higher piece price, but lower tooling costs.
*Die Casting   : 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.

Alloys
Aluminum Casting Alloys - LM Series BS 1490 1970

Uses and General Remarks
LM0 Mainly used for sand castings for electrical, chemical, and food applications.
LM2 One of the two most widely used alloys for all types of die castings.
LM4 The most versatile of the alloys; has very good casting characteristics and Is used for a very wide range of applications. Strength and hardness can be greatly increased by heat treatment.
LM5 Suitable for sand and chill castings requiring maximum resistance to corrosion, e.g. Marine applications.
LM6 Suitable for large, intricate, and thin-walled castings in all types of moulds; Also used where corrosion resistance or ductility is required.
LM9 Used for applications especially low-pressure die castings requiring the characteristics of LM6 but higher tensile properties following heat-treatment.
LM10 Mainly used for sand and chill castings requiring high strength and shock Resistance. Requires special foundry technique; heat-treated.
LM12 Mainly used where a very good machined surface finish and hardness is required.
LM13 Mainly used for pistons.
LM16 Suitable where high mechanical properties are desired in fairly intricate sand or chill castings. Requires heat-treatment.
LM18 Combines good foundry characteristics with high resistance to corrosion.
LM20 Mainly used for die castings. Similar to LM6 but a little better machinability and hardness.
LM21 Generally similar to LM4-M in characteristics and applications but better machinability and higher proof strength.
LM22 Used for chill castings requiring good foundry characteristics with good Ductility. Requires heat treatment.
LM24 One of the two most widely used alloys for all types of die castings.
LM25 Suitable where good resistance to corrosion combined with high strength is required.
LM26 Mainly used for pistons as alternative to LM13.
LM27 A versatile sand and chill casting alloy introduced as an alternative to LM4 and LM21.
LM28 Piston alloy with lower coefficient of expansion than LM13. Requires Special foundry technique.
LM29 Same as LM28 but lower coefficient of expansion.
LM30 For unlined die-cast cylinder blocks with low expansion and excellent wear resistance.

History of Superkino Equipments Pvt. Ltd.

Late Mr. Sitaram Shah, Chairman of the company launched a non-ferrous foundry in early sixties, specifically to cater an engineering units in and around Bombay. To build on this foundation, a full fledged machine shop facility was set up where most of the castings were machined before being shipped to the customers, in late sixties.
