Get A Free QuoteWe offer a comprehensive range of injection molding processes to meet diverse project requirements — from commodity plastics to engineering-grade materials and specialty processes.
High-volume production of precision plastic parts using 30–1800 ton injection molding machines. Wide material selection including ABS, PC, PP, PA, POM, and more.
LSR injection molding for flexible, biocompatible parts. Ideal for medical devices, seals, gaskets, and food-grade products requiring high temperature resistance.
Produce complex metal parts with the design freedom of plastic molding. MIM combines high material density with excellent mechanical properties for demanding applications.
Multi-material molding process that bonds a soft-touch or colored outer layer onto a rigid substrate. Perfect for ergonomic grips, seals, and aesthetic enhancements.
Place pre-formed metal inserts into the mold cavity before injection. Creates permanently encapsulated components ideal for threaded inserts and electrical contacts.
Rapid tooling and expedited production for prototypes and bridge volumes. Get molded parts in as fast as 5–7 business days using aluminum tooling.
Injection molding is the process of injecting molten plastic or metal feedstock into a mold cavity under high pressure, allowing the material to cool and solidify into the desired shape. It is the most widely used manufacturing process for producing high volumes of identical plastic parts with exceptional repeatability.
The process is highly versatile — supporting a vast range of thermoplastic and thermoset materials, complex geometries, tight tolerances, and various surface finishes. From tiny medical components to large automotive panels, injection molding delivers consistent quality at scale.
At SHBD Metal, we combine advanced injection molding machinery with decades of tooling expertise to produce parts that meet the most demanding specifications.
Refine your part design with DFM analysis, optimize gate location, draft angles, and wall thickness for manufacturability.
Machine precision mold tooling in aluminum (rapid) or hardened steel (production) per SPI classification standards.
Select the optimal material from 100+ grades. Molten material is injected into the mold cavity under controlled pressure and temperature.
The molten plastic cools and solidifies inside the mold, then ejector pins push the finished part out of the cavity.
Post-mold operations including trimming, surface finishing, assembly, and rigorous quality inspection before shipment.
Select the right tooling class for your production run. SPI standards define mold durability and expected cavity life.
| Class | Description | Material | Cavity Life | Best For |
|---|---|---|---|---|
| 101 | Premium Production Mold | Hardened Tool Steel | 1,000,000+ cycles | High-volume, tight-tolerance production |
| 102 | Standard Production Mold | Hardened Tool Steel | 500,000–1,000,000 cycles | Medium-to-high volume production |
| 103 | Bridge/Prototype Mold | Aluminum or Soft Steel | 100,000–500,000 cycles | Low-to-medium volume, bridge tooling |
| 104 | Rapid Prototype Mold | Aluminum | 500–10,000 cycles | Prototypes, test runs, small batches |
| 105 | Temporary Mold | Aluminum or Soft Steel | Up to 500 cycles | Very low volume, quick-turn samples |
Rapid tooling production
SHBD Metal manufactured a complete tail light assembly using rapid aluminum tooling. The project required precision optical-grade surfaces, complex internal geometry for LED mounting, and strict dimensional accuracy for sealed assembly.
The tool was fabricated in 12 business days, with T1 samples delivered in 15 days. The customer approved the first samples with minor cosmetic adjustments, and full production of 300 units was completed within 3 weeks.
A diverse range of industrial-grade thermoplastics is available for your molded parts, providing flexibility for both prototyping and production.
Select the right surface finish grade for your injection molded parts. SPI grades define the texture and gloss level of the mold cavity surface.
| Grade | Description | Surface Roughness | Typical Application |
|---|---|---|---|
| A1 | Grade #1 Diamond Buffed | 0.012 µm Ra | Optical lenses, high-gloss cosmetic parts |
| A2 | Grade #3 Diamond Buffed | 0.025 µm Ra | Premium cosmetic enclosures |
| A3 | Grade #6 Diamond Buffed | 0.050 µm Ra | High-gloss panels, transparent parts |
| B1 | 600 Grit Paper | 0.100 µm Ra | Semi-gloss automotive interior parts |
| B2 | 400 Grit Paper | 0.125 µm Ra | Medium-gloss appliance parts |
| B3 | 320 Grit Paper | 0.160 µm Ra | Standard matte finish |
| C1 | 600 Grit Stone | 0.200 µm Ra | Matte textured enclosures |
| C2 | 400 Grit Stone | 0.320 µm Ra | Industrial housings |
| C3 | 320 Grit Stone | 0.500 µm Ra | Functional parts, hidden surfaces |
| D1 | Dry Blast Glass Bead | 0.800 µm Ra | Textured matte finish |
| D2 | Dry Blast #240 Oxide | 1.200 µm Ra | Coarse matte, non-slip surfaces |
| D3 | Dry Blast #24 Oxide | 1.800 µm Ra | Heavy texture, grip surfaces |
