TOOLING

IN-HOUSE TOOLING CAPABILITY

To ensure manufacture cost reduction, quality consistency, and slow but sure business growth, a division to design and fabricate tools was implemented in 2002 with Solid Edge CAD to safeguard our field perfection in cold forming. To that avail, the infinite pursuit for Tool Lifetime Optimization has since become an endless curriculum to Delteks.

Various states of complex stress-strain are simultaneously present when cold forming tools are cyclically loaded. To deal with this unbeatable reality, our targeted goals are two-fold.
(1) In exploring optimum marginal efficiency brought by increase in pre-stressing of dies (i.e. tool material selection) and stiffness of tool assembly (i.e. heat treatment of tools), a positive correlation is there between both increases and tool life.
(2) In handling with die geometry itself, a process simulation module capable of calculating multi-axial damage parameters shall be indispensably required.

There are quite a few commercial FEM packages in the market. Each of them is impressive for their disciplinary specialization. But the only fly in the ointment has been none of them offer the possibility to calculate multi-axial damage parameters to the tool materials applied, making predictions of expected tool life virtually impossible.

Nevertheless, we are about an inch close to building a simple but highly referable FEM simulation module for the estimation of tool life and location of cracks. TLOS (Tool Life Optimization Simulation), as we plan to call it, will carry manufacturing at Delteks to next level of optimum tool lifetime as well as lowest machine shutdown frequency.

COMPANY PROFILE

Established in 1985, DELTEKS started with manufacturing of Cup Point Square Set Screws and Hex Flange Bolts for garage/conduit and grain bean industries. In 1992, first 4-die 4-blow former was facilitated to manufacture jackshafts for rider mower clients. Today, DELTEKS possesses a fleet of 31 state-of-the-art Bolt/Part Formers along with a full category of high-tech QC/QA inspection apparatus.

For nearly 25 good years in business with a simple mind of rationalism, Delteks deserves the pride in the magnitude of responsibility it has been taking in handling complaints from its customers. And in quite a few occasions additionally, we have humbly refused to deal with companies who are clients to our customers. That kind of righteousness and loyalty gives Delteks the winning edge and enables us to survive better than others during worldwide economic recession.

MANUFACTURING CAPABILITIES

Selective Material Processing (SMP) from stem to stern plays an important role in cold forming at Delteks fabricating customers’ complex parts from concept to reality. Before nanostructured wire coil generated by HPSPD (High-Pressure Severe Plastic Deformation) becomes as commercialized as hot-rolled aluminum-killed SAE1010 steel, various compensating processing remains indispensable in a give-and-take brainstorming for both the ductility and strength of a cold formed part.

Economy of Scale (ES) is adequately reached in several other operations at Delteks than the one commonly known between tool/die amortization volume and unit cost of a part. In manufacture programming specifically, Economy of Scale has to be there between the number of dies/blows required and optimum manufacturing efficiency, tool life estimate by FEM and number of tool to build for each die/blow, and etc.

Multi-Stage Cold Forming process means more to Delteks for how customers’ parts or components are effectively and efficiently made in conformity with specifications than out of what variety of forming machines that made your parts. To that avail, some certain equilibrium is always reached among various characteristics of the machine simulated for manufacturing a specific part. Such as DKO and PKO (Die Kickout and Punch Kickout) strokes of all dies/blows involved, adaptability of targeted cutoff diameter and length in a machine’s maximum and minimum limits, and etc.
