Injection Molding Capabilities
Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. It is most commonly performed with thermoplastic and thermosetting polymers. Granular plastic is fed from a hopper into a heated barrel where it is melted, then forced under high pressure (typically 10,000-30,000 PSI) into a mold cavity. The material cools and solidifies into the shape of the cavity. Injection molding is the most common method for manufacturing plastic parts, producing billions of parts per year worldwide. It is ideal for high-volume production where tooling costs are amortized over large quantities.
±0.002" (±0.05mm) standard; ±0.001" achievable with precision molds
4-12 weeks for tooling; 1-4 weeks for production after tooling
$5,000-$100,000+ for tooling; $0.10-$10 per part in production

Injection Molding in San Diego — FAQ
How many Injection Molding providers are in San Diego, CA?
The San Diego-Chula Vista-Carlsbad metropolitan area has approximately 2,200 manufacturing establishments, many of which offer injection molding services. The area employs about 48,000 manufacturing workers, ensuring a skilled workforce for your project.
How many parts before injection molding is cost-effective?
Injection molding typically becomes cost-effective at volumes above 1,000-5,000 parts, depending on part complexity and tooling cost. For very simple molds, break-even can occur at a few hundred parts. For complex molds costing $50,000+, volumes of 10,000+ are usually needed.
How long does it take to make an injection mold?
Simple single-cavity molds take 4-6 weeks. Complex multi-cavity molds with side actions and precision requirements take 8-16 weeks. Rapid tooling options (aluminum molds) can be ready in 2-3 weeks for prototyping and low-volume production.
What plastics can be injection molded?
Most thermoplastics can be injection molded including ABS, Polypropylene, Polyethylene, Nylon, Polycarbonate, Acetal, PEEK, PPS, TPU, and many more. Some thermosets and elastomers (silicone rubber) can also be injection molded with modified processes.
What is the typical cycle time for injection molding?
Cycle times range from a few seconds for small thin-walled parts to 30-60 seconds for larger thick-walled parts. A typical cycle for a medium-complexity part is 15-30 seconds, including injection, cooling, and ejection.
