Plastic tooling for small series low-volume production, results in high expense during the development of a product. And when the product development requires the fabrication of prototypes with a selected final production technology such as (injection molding) this is when rapid molding allows you to get dimensionally accurate prototypes with less expense from conventional plastic parts. Parts for the medical design industry as well as other industrial sectors, include components like enclosures, sensors, and automated IT storage equipment.
Similar to the conventional method, rapid molding does affect how parts are created. Plastic in the solid form of resin pellets are loaded into an injection molding hopper machine. Heated barrel in the machine melts the plastic material and a screw forces the melting plastic in the mold. Then material cools and solidifies. When the machine is open the mold and parting line and ejector pins pushes the part out.
The method is based on using 3D CAD data that have been processed and uploaded to machine. Rapid tooling utilizes both conventional method as well as rapid prototyping to support prototyping small quantities, bridge tooling, and small series volume production parts.
Although, additive manufacturing (3D Printing) processes as such; SLA, SLS, FDM works fine for fit, form and testing, the additive manufacturing process is not a match substitute for testing real molded parts. Rapid injection is a fast way to fix product design flaw problems when the initial designs are still being decided upon.
Aluminum or steel tooling range in size from 75-300 tons. To accommodate molded test parts from 50, 100, 1,000, and 10,000 parts and rapid prototype in the same thermoplastic resin to be used in production.
Unlike other automated methods, there are no restricted design limitations for our injection-mold rapid process. No limited choices of resin materials or limited flexibility in the tooling process. Trying injection molded fast turnaround parts requires a 3D STEP file also included are useful information about expected lead-time, pricing various quantities and any additional requirements.
