Benefits of RH/RC processing using Surface Induction: -Cost is less than other technologies both equipment and energy part to part. -Dimensional Stability of finished part. -Reduced warpage and stresses -Sink reduction or elimination -Elimination flow lines, gate blush -Burying glass or filler content in resin as well as class A on cellular molded products. -Reduced and/or elimination of metallic streaking -Enhanced texturing. -Enhanced Chrome adhesion and overall quality. -Piano black finishes -Thin wall molding. -Reduced tonnage requirements. -Less stress on tool, ejection, slides and cams tool is maintained at a constant tower temp. -Enhanced cycle time. Takes less time to elevate surface temperature and less time to cool surface temperature because there is a mechanical advantage over all other RH/RC technologies. Surface induction only heats the surface whereas other technologies heat and cool the surface from the inside of the mold out to the surface.

Surface Induction molding is superior to all other Rapid Heat/Rapid Cool processes. Other RH/RC methods lack the one mechanical advantage that Surface Induction possesses, Other processes including Steam, Cartridge heater, in tool Induction, heat the tool surface from the inside out, then require the tool to be cooled from the inside out as well. This requires additional time and energy to heat and cool the tool surface, plus these methods inherently put the tooling under tremendous stress. Surface induction only heats the tool surface with .5 to 1.0 mm penetration putting much less stress on the tooling. Surface induction uses less energy and time to achieve the desired results. Our systems are lower cost, plus use less energy than all RH/RC methods and do not require unique injection mold tooling. We offer rental units, leasing options and purchase options for our units. We manufacture our induction units domestically, we service and warrantee our units and should the require service or repair we are local. Our proprietary coil design and construction is superior to our competitors offering less energy to provide the same results. We are also able to induce complex geometry where our competitor's struggle with this. Our coils are designed and built with repetitive production requirements in mind. We can manufacture coils for use on any induction unit, our coils are not matched to our induction unit.

Shown below are the benefits of RH/RC molding Elimination/Reduction of knit lines. Elimination/Reduction of gate blush. Superior surface finishes including Piano Black and Grain enhancement. Dramatically improved Chrome Adhesion. Less stress molded into part reducing warp and coining. Burying of glass and fillers in resins. Elimination/Reduction of sinks. Ability to design product with thinner walls and ribs. Ability to manufacture High Melt temp resins such as Polyester providing highest quality. Dramatically improve Automotive lens quality and clarity. Shown below are the benefits of Surface Induction molding over other RH/RC methods Improvement of Cycle Time vs. other methods. Less energy use per shot. (Average cost for 300 ton sized part is $0.003897 per 4 sec heat up.) Much lower capital costs. Less maintenance and chance of down time. Tooling does not require special design and Build requirements. Adding conformal cooling enhances actual cycle times instead of making other methods stay inside typical cycle times. Puts less stress on tooling making hybrid tooling options more feasible. You can apply this technology to existing tooling already in production.

More detailed view of how Surface Induction optimizes your part quality and reduces cycle times. Induction Coil is mounted to current Robot end of arm and can utilize pick in place function in conjunction with presentation of induction coil to tool surface. Overall tool temperature is maintained at 50-70 degrees F. Cycle Starts and Robot or SIT supplied automation presents induction coil to tool surface. Upon presentation of coil to tool surface, Coil is energized, creating an eddy current to surface, this eddy current heats tool surface, approximately .5 to 1 mm deep. The tool surface is heated 50-100 degrees F higher than the optimal melt temp of resin to be injected, when the eddy current is removed the tool surface begins to cool immediately. Resin is injected into tool, Tool temp is maintained at a constant 50-70 degrees F. This allows the tool surface to cool rapidly allowing for a reduced hold and pack time. Product can be de molded quicker.

FAQ -Does The Coil Get Hot? –The induction process does not heat the coil, the coil will get hot by the heat of the tool radiating to the coil. The coil is cooled to keep it at a safe operating temperature. The coil can be touched by a technician. -Does Coil Actually Touch Tool Surface, Will it scratch surface? –No the coil is actually presented to the surface but never actually touches the tool, it is designed to maintain a distance of 1 to 1.5 mm clearance. -Can Surface induction be applied to complex geometry? –Yes our coil design and construction allow for induction to complex geometry, even undercuts can be induced. -Is Induction safe? – Induction is safer than most other RHRC processes, our units have fail safes built in to keep the unit and the press operator safe at all times. -Can I apply to an aluminum tool? – Yes but unfortunately it is not nearly as efficient as a magnetic steel. Our units allow a technician to change frequency to maximize if an aluminum tool needs to be induced, applying a .5 to 1mm thickness of plasma coated nickel is preferred. -Is there a royalty paid for the use of this technology? – No, there are no royalties paid. -Does the coil “Wear Out”? – No the coil does not “Wear Out” but it is subjected to normal wear and tear and may need replacing periodically.
