Chicago Dowel’s Quality Control process begins at the lumber mill stage. Good quality wood products must start with good quality lumber. Logs are milled into cants, then sawn into boards. After stacking, the boards are slowly kiln-dried to 6-8% moisture content. Proper kiln drying is a crucial stage of lumber production. If lumber is dried too quickly, warped boards will result. Lumber not dried well enough will cause the final wood product to shrink after machining. Lumber dried too well will result in cracked boards. Lumber is finally loaded onto trucks for shipment to Chicago Dowel where quality production continues.
Quality Control continues throughout our entire manufacturing process. Dowel pins are constantly measured for proper diameter, length, and moisture content. Dowel pin sorting is arguably the most important part of the Quality Control process.
The pins are first hand and screen sorted. Then, to ensure dowel pins arrive at the customers’ dock virtually defect-free, they are passed through Chicago Dowel’s proprietary, state-of-the-art electronic sorters.
Chicago Dowel’s stringent quality control program makes its pins the dowel pins of choice for end users most of whom use today’s sensitive dowel insertion equipment.
Of course precision sorted dowel pins means less down time for our customers. Less down time naturally leads to higher profits.
