Finding the Very Best Supplier—Another Factor to Consider

Proficient Sourcing helps buyers find good suppliers for custom manufacturing, so we look for thought provoking purchasing articles. Recently, one article dealt with the value to buyers of long term relationships. Another article asked whether big savings meant prior buyers were not performing well. Both articles focus on relationships created at a specific time of a buyer’s need. By omitting a simple step the best potential supplier may be overlooked. Job shops’ available capacity rises… Read More


Capability: Turning work

If you need a versatile company to do turning work, consider this. One specific company has these certifications: AS, ISO, ITAR, Service Disabled Vet owned, HubZone, EDGE (OH), and ITAR. The company specializes in turning work. From swiss turning, multi-spindle, 5 and 6 axis CNC turning centers, CNC lathes, and 3 rotary transfer machines. This permits projects from prototypes to high volume production, and the company also features engineering assistance, design support, subassembly and inventory… Read More


Single Sourcing vs Multiple Sources for Custom Manufacturing

Both sides of this issue have emerged in our efforts to help buyers with suitable candidates for manufactured items. We’ve worked both sides—insistence on a sole source as well as finding competitors for a multiple source situation. So we have thoughts on the subject and hope you will offer additional ones in the comments below. First, a single source success story: we were asked to find a sole source for an automotive project. The project… Read More


Get better RFQ responses!

Get better RFQ responses!  We at Proficient Sourcing live and die with RFQ traffic, and it seems that the buying population would be interested in better responses. Maybe we can help. Most of what we see is an RFQ to manufacture or fabricate some metal or plastic part. The RFQ wants a price and delivery for a stated quantity, and sometimes an “answer by” date is provided. That’s about all we usually see. It’s also… Read More


Custom machinery: building and refurbishing

Custom Machinery: New business may involve the manufacture of some new piece of equipment—a complete assembly or perhaps a new or modified section of existing machinery. A similar issue might be the need to refurbish, modify, update, or even perform major repairs, on some machinery or equipment. If you anticipate such requirements, we have good news.  If your situation can fit under 15 feet in height and does not require more than 5 ton bridge… Read More


Dip Moldings

Many hand tools, levers, grips and a wide range of other items are made with plastic (plastisol) coatings. Dip molding is the technique for providing plastisol coating, and other applications include electrical insulators, caps, plugs and coatings for color coding. The process can produce both an external part coating or an item made inside a mold. Since plastisol is somewhat elastic, complex parts can be stripped from molds rather easily. Plastisol is a vinyl compound,… Read More


Tolerances: Anyone paying attention?

Here’s a problem we see rarely; never is when we’d prefer to see it. In a previous newsletter we noted an article that suggested NOT answering a request for proposal, and we thought that a very bad idea. However, here’s a case where it might be correct. One contact requested a quote for machined plates that fit together. The finished item was a machine base, so the parts needed to match up on the edges… Read More


An alternative to progressive die stamping

Parts assumed to require progressive dies and stamping presses may be candidates for fourslides—a common wire forming machine not routinely found in stamping companies. If you require a progressive die capability, it might be worthwhile to investigate the fourslide option. In general, set ups for fourslides are probably more complex, as the tooling is bolted onto the machine with timing accomplished via cams and slides. On the other hand, there may be less waste, less… Read More
