Sourcing Areas of Specialization

Solenoids

• DC Solenoids-open frame

• DC Solenoids- enclosed

• Self Latching Solenoids

• Tubular Solenoids

• Push-pull Solenoid

• Rotary Solenoids

Solenoids are available in standard and custom design.

**Important design considerations on all solenoids are pull force, duty cycle/Stroke and operating voltage.**

Valves

Custom built valves for the fire suppression industry are suited for use across environments such, a petro-chemical, gas, power station, paper & pulp, 

pharmacy, hygienic food, brewing, chemical, auto & motorcycle, utilities.

Cast Metals

Die Casting:

Best suited for small to medium size parts with higher volume requirements. 

100% recyclable material in some applications. Cast parts are preferred over plastic because they offer better strength, tolerate higher temperatures, and have a lower impact on the environment.

Advantages include minimal secondary finishing operations, high production runs, economical, tighter tolerances, thin walls, and consistency.

Disadvantages for die cast parts are weight (less than 30 grams/1oz) and size restrictions (24 inches/600mm), high initial costs, and some material limitations.

Best suited materials are copper, lead, aluminum, zinc, and tin based alloys

Investment Casting:

Best suited for parts that are small, include intricate design, and demand high reliability.

Advantages are accuracy, consistency, tight tolerances, thin walls, finished appearance, complex shapes, variety of alloys, and low material waste.

Disadvantages are increased piece price due to additional manufacturing processes, individual patterns required for each casting (increase tooling costs), and limited dimensions.

Most commonly used alloys are carbon, tool and alloy steel, and multiple grades of Stainless steel.

Sand Casting:

Best suited for parts that are simple in design and may be a large size

Advantages include low cost molds, low cost piece price, larger parts, and it produces less waste since material can be added to next run.

Disadvantages include surface finish, limited wall thickness, decreased tolerances, and lower porosity.

Common materials are aluminum alloys, brass alloys, cast iron and cast steel.

Forging

• Best suited to applications where tensile strength, ductility, impact and fracture toughness, along with material fatigue, are important.

• Advantages include optimal grain flow. Forged parts are free from internal voids and porosity that may be found in cast parts. The main characteristic of a forged part is integrity of the part.

• Other advantages include near net shape and require less secondary processes.

• Forged parts also generate very little scrap material.

• This process is advantageous in any applications that involve safety issues including aerospace, automotive, valves, and fire suppression.

• Disadvantages can be higher tooling cost, reduced tolerances, and higher piece price on low volumes.

Finishes

Powder coat, paint, e-coat, black anodize, black oxide, polish, buff, flat, shine, anodize, silk screen, electroplate, chromate, passivate, nickel plate, electroless nickel plating,

These processes are controlled to offer the highest quality parts to market.

Machining

Precision machining is paramount in industries demanding tight tolerances. S.O. Sales has been a top tier supplier for over 30 years.

Transformers

Built to meet Agency Standards including UL, CSA, IEC-65, BS-415, SEMKO and VDE. Typical Applications include power supplies, telecom, LAN, lighting, industrial electronics. Transformers are manufactured in China, Thailand, Indonesia, Taiwan and Singapore.

• Core sizes include EI 35 thru 66.

• Both single or dual primaries are available.

• Both custom and standard transformers are available.
