Based on our knowledge of the materials, metal fabrication and manufacturing technology, engineering team assesses and provides recommendations for ease of manufacturing, durability, quality, and cost containment. Our engineers work closely with your product designers to develop the best solution for your requirements, using 3D CAD design software and other advanced technology. Our goal is to recommend the best way to design a part to reduce the risk of failure, increase productivity, and contain costs. With our extensive in-house engineering resources, we can make modifications quickly if a flaw is discovered during the design phase.

A component’s function should dictate its design. Ask our experts about design feasibility and some of the practical aspects of the manufacturing process. Design simplicity is cost effective.

Clearly identify all dimensions that are critical. Specify exactly what the tolerances need to be. Tighter tolerances can increase cost, so allow for flexibility of non-critical dimensions.

Material type, thickness and temper can significantly affect the cost of a finished part. Carefully relate the material used to its end use. Feel free to discuss your material issues with our in-house experts.

Realistic lead times for quality tool building and manufacturing of your part is essential for cost effective pricing and production.

Accurate projections of current and future needs will help determine the best manufacturing process for your requirements. Our unique stamping and metal fabrication processes can minimize tooling and total part cost. If possible, let us know your future requirements as well as your current needs. It could save you a bundle.

Having “families of parts” produced by one metal fabrication supplier can result in significant overall savings. Let us give you a quote for similar stamped / fabricated parts to see if you can reduce cost.

Determine the best shipping method based on any special handling requirements or time-in-transit. If your parts are to be delivered to a specific location, be sure to ask us about our in-house delivery service. Our logistic services could save you time and money.

 CLR- Center Line Radius. Typical CLR is 3x the OD of the tube without mandrels. It is possible to bend on a 1 or 2xD bend, but not without more complex tooling. Tooling costs also increase when comparing a plug mandrel to 3-ball mandrel & wiper die. The tighter the radius, the more tooling required and the more expensive the part.
 Use the same CLR for all bends unless prohibited by design restraints.
 Straight between bends. Allow 3x the OD of straight for clamping between bends and from the edge of the tube. This reduces the overall cost of part by reducing additional trim operations and increasing the bend rate. Bends closer than 3xD require compound tooling increasing tooling cost and reducing bend rates.

 Minimum hole diameter. General rule of thumb is minimum hole diameter is equal to or greater than the material thickness. A 5/16"DIA hole can be put in 1"thk plate but not with great speed and reliability. The cutting speed and pierce routine must be adjusted which increase time and part cost.

 Use the same ISR for all bends unless required
 A hole or slot put near a bend will distort. Critical holes placed in the affected bend area will have to be put in after bending or opened up resulting in an additional operation and added cost.

 The tighter the tolerance, the greater the cost. Don' t pay for something that is not needed.

 Zechin Industries also provides reverse engineering solutions with the help of CAD/CAM-enabled touch probe laser Inspection systems. Our reverse engineering team helps us to create quick drawings from old parts and templates. Furthermore, our CAD/CAM systems also ensure that the time taken from drawing to cutting is limited to only a few minutes.
