Customizing Options

If we’ve learned one thing in our more than50 years of business, it’s this: the mind ofman has an endless capacity to dream —and to turn those dreams into reality.

Ideas that were science fiction when westarted out in business are now commonplaceproducts in millions of homes.

We’ve also learned that men who havedreamed the dreams and found ways tomake them come true, are, for the mostpart, dedicated, demanding perfectionists— perfectionists who expect every detail to coincide with their ideas.

Complete In-House OperationWe are proud to have earned a reputationas a company with the ability to respond to the most exacting specifications and tosurpass every expectation. We attribute a lot of it to the fact that every phase ofproduction is handled in-house.

We do our own design and engineering,prototyping, our own tool making, plasticmolding, screw machining, metal fabrication,automatic drilling and tapping, hot stamping,silk screening, laser etching, photo etching,painting, finishing, and much more.

The Highest Quality withthe Shortest Lead TimeWe control every aspect of production. Thisallows us to remain competitive while alsoproducing the highest quality product. Wecan maintain an extremely high level ofquality control, as well as, meet the tight-est delivery schedule requirements.

Stock and Special ToolingNaturally we offer a complete line of stocktooling as well as the ability to modify exist-ing molds. But, just as important, we cantool from scratch— to your original designs.

We can make knobs and dials no matterwhat that knob or dial might be — whatever

it might look like. If you can enclose a plasticpart in your hand, we can mold it better,faster and more efficiently by the use of ouruniversal pocket molds. This means that ourcustomers can take advantage of tooling, acavity or core only, at low cost, yet still haveproduction costs of a multi-cavity mold.

Any Size, Any ShapeOur standard knobs come in sizes from1/4 to3 inches in diameter. And, while they comein an infinite variety of shapes, if you needone that’s different, we can design andmake it for you. We already make knobs tofit just about every shaft that there is.

MaterialUnless you require a specific material, allElectronic Hardware knobs and dials aremolded thermoplastic. So, you get knobsthat have the characteristics that you need— knobs that are strong, heat resistant,and have dimensional stability. But, we alsocan make knobs from any thermoplastic orthermoset material that you request.

TrimWe’ll add any kind if inlay or cap, diamondcut, decorative, spun, formed cap, whatever.Or, any finish: metallic to mylar.

On the following pages you’ll find many ofthe standard knobs and dials that we make.But if you don’t see what you’re looking for,give us a call— because we can make exactlywhat you need.

Secondary OperationWe make it possible for your part to bemolded and finished under one roof. Silkscreening, sonic welding, automatic drillingand tapping, hot stamping, pad printing,spray painting, laser engraving and solventbonding are all options that are readilyavailable. We’re prepared to do it immedi-ately — with quality. This all translates intocompetitive piece prices for your parts. TheBottom Line!

Technical Data

Resins–much of the growth of the injection molding industry is due to the continuing ability of resin suppliers to offer new and improved engineering materials. Today resins can meet specifications for mechanical, thermal, electrical and impact demands increasingly competitive in performance to metal at reduced processing costs.

EHC’s participates in an ongoing evaluation process of new resins. Moldability, ease of processing and decoration are some of the analysis conducted. This process provides for a continuing effort to improve current production needs and prepare for future program demands.

• Good Mechanical Strength is of primary concern when choosing our materials. Where high mechanical strength is needed numerous reinforcements are used including glass fibers, mineral fillers, glass microspheres, all products that improve impact resistance.

• Electrical Resistance or Insulation make the use of EHC plastic products especially suited in electro-mechanical environments.

The plastic materials used in EHC parts have been carefully selected to meet the functional and aesthetic requirements of each product.

Thermoplastic – Materials with technical characteristics such as: ABS, nylon, TPR, polyamide, acetyl, polypro-pylene, polycarbonate, PPO and polyester resins. These materials are not always interchangeable.

InspectionStandardParts are considered commercially non-acceptable if an imper-fection is visible when viewed at arm‘s length distance undernormal lighting conditions. Parts will be viewed for a period not to exceed 3-5 seconds in daylight (or fluorescent light of approximately 70 foot candles) with the unaided eye at normalviewing distance of 24 inches, in the normal viewing plane.

SpecialJewelry-type inspection will be reflected in a higher unit-cost.Customer to provide EHC with written notice in advance of placement of order.

Chemical ResistanceContact manufacturer for resistance factors prior to usage with chemicals.

Surface Finish1. Gloss: Parts produced from a highly polished mold, or 2. Satin: Parts produced from a textured mold to remove

glossiness, or
