Howard Industries Excels at DeliveringExactly What Our Customers Want.

Life-Cycle CostReductionHoward Industries’Customer Assistance Teamexcels at helpingcustomers find ways toreduce cost. Using activity-based cost analysistechniques, ourcommercial and technicalexperts help customersanalyze costs throughoutthe transformer supplychain, identifying andeliminating activitieswhich add cost but havelittle or no value.

Quality and ReliabilityBuilt into EveryTransformerHigher quality meanslower failure rates … andthat translates into loweroperating and mainte-nance costs. Higher qualityalso means customers canreduce cost by reducing oreliminating incomingreceipt inspection andtesting.

At Howard Industries ourQuality AssuranceProgram is designed toachieve the high level ofquality required by ourmost demandingcustomers. Abandoningthe traditional manufac-turing-only focus, we havecreated a quality systemthat links all aspects of thecompany’s operationsincluding Marketing,Engineering, ManagementInformation Systems,Manufacturing, Shippingand Accounting to makesure that not only ourproducts, but everythingwe do for our customers isof the highest quality.

Howard Industries’ qualitymanagement system hasearned ISO-9001 certifica-tion. ISO-9001, the mostcomprehensive standard inthe internationallyrecognized ISO-9000 series,covers design, manufac-turing and servicingsystems. This achievementdemonstrates HowardIndustries’ commitment tocontinuous qualityimprovement.

Automated and robotic welders perform 100% of all oil-compartment seam welds.

Computerized final test stationsperform a complete series ofelectrical tests prior to shipment.

Electrostatically applied powder paint providesa durable, corrosion-resistant finish.

Designs Optimized forSuperior Performanceand EconomyOur design philosophy isto provide our customersexactly what they want.That means transformersthat are individuallydesigned in preciseaccordance with eachcustomer’s specifications.Each transformer design isoptimized to satisfy thecustomer’s needs at thelowest possible cost.

Howard’s ProductAutomated Design System(PADS) is driven directlyby each customer’sspecifications to insure thatall the necessary

requirements are satisfied.PADS synthesizes eachtransformer design andproduces all criticalmanufacturing documents.PADS then links with asophisticated computer-integrated-manufacturing(CIM) system to automati-cally carry-out fabricationon the factory floor. ThePADS and CIM systemseliminate manualprocesses and theirinherent inefficiency anderror, and make it possibleto quickly modify andcustomize transformerdesigns.

AdvancedManufacturingHoward transformers aremanufactured in thelargest, most advancedfacility of its kind. The 1.6million square foot Laurel plant is the result of arecent three-year, $50million expansion project,which saw the introduc-tion of the latest and mostsophisticated robotics andautomated processequipment available.
