One does not work plastics in four decimal places (.0000 or tenths) as metal:

·         Our industry generally works in thousandths or three decimal places (.000).

·         Moore-Addison consistently grinds, turns and mills parts to +.0015.  We SAW to +.1/64^th (.015) and do ROUTER work to +.005

·         But, our competition works to only  +.010.  Their sawing is generally to 1/32.

False readings can occur if plastic parts are inspected the same way as metal parts:

·         For instance, the sharpened point of an indicator might read between the laminations of a phenolic part rather than the true surface as it would on steel. 

·         Measuring gauges are typically made out of steel and are used to measure softer plastic parts.  The plastic part can be forced to give by the harder metal gauge and present a false reading.  We have had to meet with inspectors to agree on the “class of fit” for plug and thread gauges.

·         It’s good to get a mating part and agree how it will fit.  A nut for a bolt or a faceplate on which a cover fits.  Often the mating part is “more expensive” than our plastic part, so if there is a problem, it will tend to be blamed on the least expensive and easiest to replace part.

Moore-Addison inspects material inbound, parts outbound and in-between:

·         Material is thoroughly checked as the skids arrive on our dock.

·         The company employs a full time Quality Assurance Manager.

·         The foreman inspects parts arriving in his department and before they go out.

·         Everybody inspects the parts as they are made/come off the machine.

·         Final inspection occurs in shipping where the obvious overlooks are confronted.  For instance, a gear blank is missing its bolt circle holes.

·         Normal production controls and inspection procedures at Moore-Addison meet or exceed ISO9000 standards.  We are moving to documentation and certification.

Light assembly and Fabrication:

·         INSERTS

·         Are called for so the customer can bolt up to the part we’re making.

·         We ask that the customer provide the inserts from their stock.

·         If Moore-Addison installs the inserts, we know the hole is the right size and the inserts will fit properly.

·         If the customer specifies the inserts on the print, it is very easy for them to have replaced a $.65 insert with a $.45 insert and we don’t know until their inspector complains.

·         POTTING BOXES

·         Are used to protect a customer’s proprietary electronics from electrical disturbances and their competitors prying eyes.

·         Moore-Addison glues them up out of the same epoxy resin that is used to make the G-10/FR4 material being glued. 

·         We bend them up by not cutting through all the layers of cloth.

·         They are guaranteed not to leak.
