Capabilities

Forming		It is cost effective with shorter lead-time to form etched parts compared with a stamping process. We can form prototype quantities as low as 5 parts and production quantity of thousands of parts. It is much faster & cheaper to produce flat-blanks using an Etching process and subsequently form them using either soft tool or hard tooling die-set. Our engineers are experienced in estimating band allowance in order to minimize iterations. We have experience in forming Copper, Beryllium Copper, Phosphorous Bronze, Stainless Steel, Titanium, Nickel-Silver and other metals in thickness range of 0.002” (0.050 mm) to 0.040” (1 mm).

Plating		The following type of plating is suitable on metals such as Copper alloys, Stainless Steel, Molybdenum, Titanium, etc. Gold: as per MIL-G-45204, AMS 2422 D, ASTM B488, Types I, II, III Silver: as per QQ-S-365, AMS 2410 / 2411 / 2412, ASTM B700, Types I, III Nickel (Electro-less): as per MIL-C-26074E, ASTM B733, AMS 2404D Nickel (Electrolytic): as per QQ-N-290 / AMS 2424 Nickel (Sulfamate): as per MIL-P-27418 / AMS 2403 Tin: as per MIL-T-10727 / ASTM B545, Type 1 (Bright or Dull) Tin/Lead: as per MIL-P-81728 / AMS-P-81728

Heat Treatment		It is possible to heat treat metal sheets prior to etching since the mechanical properties do not get altered during etching process. And it is also feasible to etch and form the part prior to heat treatment.

Passivation		Although stainless steel is corrosion resistant, during fabrication processes iron particles or other foreign matter may become imbedded into the surface of stainless steel parts. These particles must be removed or they will appear as rust. With a chemical treatment, such particles may be removed which allows for the formation of a passive film on the cleaned surface.

Shape-setting of NiTi		For achieving shapes beyond etched flat configurations, Kemac can perform shape setting of nitinol components using rigid fixtures and a controlled high temperature bath. This heat treatment method is capable of reaching the required temperatures quickly and uniformly which assures consistent thermal and mechanical properties.

Electro-polish		Kemac is equipped to perform electropolishing of nitinol, titanium and stainless steel parts. This process is used to achieve smooth surfaces and to remove surface irregularities such as burrs to enhance fatigue performance. The process can also provide a uniform passive layer to enhance corrosion performance and biocompatibility.

Leak-test		Helium Leak Testing is necessary on Etched metal components that are designed to withstand very specific pressure, vacuum or hermetic environment. Precisely etched depth in a part may act as a balancer of such condition.
