What's Injection molding? How Does Injection Molding work?
Injection molding is a high-efficiency manufacturing process used to produce large volumes of identical plastic parts with precision. IMolten material (typically thermoplastic or thermoset polymers) is injected into a custom-designed mold cavity, cooled, and solidified into the desired shape. IThis method is ideal for mass-producing complex, lightweight components like automotive housings, medical devices, consumer products, and industrial parts.
Mold Design & Preparation:A two-part metal mold (tool) is CNC-machined to mirror the final part geometry, including cores, cavities, and cooling channels.Mold surfaces are polished or textured to achieve specific finishes.
Material Melting:Plastic pellets are fed into a heated barrel, where a screw mechanism melts and homogenizes the material.
Injection:The molten plastic is injected under high pressure (up to 20,000 psi) into the mold cavity through a sprue and runner system.
Cooling & Solidification:The mold is cooled (via water channels)to harden the plastic. Cooling time depends on part thickness and material properties.
Ejection:The mold opens, and ejector pins release the finished part. Excess material (flash or runners) is trimmed or recycled.

Success Stories of Injection Mold Tooling Projects
FAQs
How long does injection molding tooling last?
Tool life expectancy ranges from 50,000 to 1,000,000+ cycles, contingent upon mold material (P20 vs. H13 steel), polymer abrasiveness (filled vs.
unfilled resins), maintenance protocols, and production conditions. Regular preventive maintenance can extend tool life by 30-50%.
What are the factors in the design of injection mold?
Critical mold design considerations include: tool steel selection, parting line configuration, cooling system layout, and ejection mechanism. Additional
factors encompass processing parameters (melt temperature, injection pressure) and final part specifications (tolerances, surface finish requirements).
How much does your injection molding service cost?
Injection molding pricing is determined by multiple variables including part dimensions, tool complexity (single vs. multi-cavity), material selection,
and secondary operations. We provide customized quotations based on your specific project requirements and volume needs.
