Lean production is one of the most important manufacturing strategies to emerge in the last century. By minimizing waste, which is considered anything that doesn’t provide value in the manufacturing process, lean improves efficiency without sacrificing productivity, enabling you to deliver higher quality products to your customers at lower costs. A perceived issue with lean […]

In our last lean manufacturing blog post, we explored how making our manufacturing cells smaller has improved the use of our floor space and boosted overall factory efficiency. But the lean updates and improvements in hermetic sealing techniques and hermetic feedthroughs don’t end there.   In an effort to continually improve our manufacturing practices, and […]

Since implementing lean manufacturing principles, a topic we explore in our latest white paper, we’ve been able to improve the efficiency of our factory—making gains in safety, quality and productivity. Building on what we learned, we continue to look for new ways to eliminate non-value added tasks, which eat up unnecessary time, materials, labor, and […]

One of the key elements of a good lean manufacturing system is the ability to spin up new work cells quickly. In our case, spinning up a new cell requires us to create all kinds of custom fixtures and other tooling.   Given the broad mix of products we make, custom fixtures have become second […]

Epoxy-based integrated feedthrough technology is a proven, effective way to seal the wiring of in-tank fuel pumps, reducing assembly time and potential failure modes. Douglas Electrical Components casts epoxy feedthroughs directly into the fuel pump to form a true hermetic seal around any wires that pass through the housing. Watch our new video to learn […]

Incorporating sensing elements into sealed electrical assemblies One defining characteristic of CircuitSeal™ technology is its design flexibility. Not only can CircuitSeal work with many different types of circuit boards, but it can also integrate related electrical components to create a fully-functional, hermetically sealed electronics assembly. One such component is a sensing element.   CircuitSeal assemblies routinely […]

Of all the design decisions that affect the operation of an in-tank fuel pump, the way you seal the pump housing may top the list. A bad seal will allow liquid fuel to work its way into the housing, which will eventually corrode the electronics and potentially cause a risk of fire. Given the importance […]

Epoxy-based hermetic feedthroughs have worked well in cryogenic systems for years. But the design modifications needed to operate in these extremely cold temperatures increased the size of the feedthrough and limited your mounting options. We recently eliminated these issues with an entirely new approach to cryogenic feedthrough design. Intended for use in space simulation, laboratory and liquefied […]

We’ve shipped our share of standalone hermetic feedthroughs over the years. Increasingly, however, sealed hermetic penetrations leave our plant as a part of a value–added assembly. These turnkey assemblies typically combine our hermetic feedthrough technologies with non-hermetic connectors, printed circuit boards, flex circuits and wire harnesses. Assemblies can also incorporate strain relief, water-blocking overmolds, jacketing, shrink tubing, breakouts, mechanical subassemblies and patch […]

With medium-voltage switchgear, progress is being made with regard to finding alternatives to SF as an insulation gas. Designs that incorporate dry air or a mixture of fluoroketone, nitrogen and oxygen as the insulating gas are being explored to minimize environmental impact. Oil, vacuum and CO are other alternatives to SF. Regardless of the type […]

It’s tough enough to design safe electrical systems for hazardous locations without having to worry about the UL listings for each and every component you use. We’ve just made things a bit easier for you with a new line of UL listed explosion-proof wire bushings.   Our epoxy-based NPT bushings feature a UL 1203 listing, which addresses […]

To reduce the risk that electrical outages will cause production delays that affect our customers, we recently invested more than $500,000 in a new combined heat and power (CHP) generator for our 30,000 square foot manufacturing facility. This system works in conjunction with our existing roof-mounted solar panels, which were installed in 2012.   The […]
