service related FAQ’s
Injection molding is a manufacturing process used to produce high-precision plastic parts by injecting molten material into a steel or aluminum mold. It’s ideal for:
• Functional prototypes
• Bridge tooling before mass production
• Low- to mid-volume production runs
• End-use parts with repeatable quality
American Tooling & Machining provides:
• Rapid tooling for prototypes and pilot production
• Production-grade tooling for long-term programs
• Insert molding and overmolding
• Multi-cavity or family molds
• Post-molding operations like assembly, pad printing, and packaging
We work with a wide range of engineering-grade resins, including:
• ABS, PC, PP, POM (Delrin), PA (Nylon), PMMA (Acrylic), HDPE, TPU, TPE, PPS, PBT
• Custom material or color matching available upon request
Need help selecting the right resin? Our engineers will recommend the best option based on your part’s application.
Typical lead times:
• Rapid tooling and first articles: 10–15 business days
• Production runs: 2–4 weeks, depending on part complexity and finishing
• Expedited options may be available for urgent projects
Tool life depends on the material and usage:
• Aluminum molds (prototypes/bridge tools): 3,000–10,000 shots
• Steel molds (P20, H13): 50,000+ shots
We’ll advise based on your target volume and lifecycle requirements.
• Typical tolerance: ±0.1 mm for well-designed parts
• Tighter tolerances may be achievable depending on geometry, material, and tooling
• A detailed 2D drawing with tolerance callouts is recommended for critical dimensions
Yes! We provide Design for Manufacturability (DFM) analysis with every quote.
Our engineers will review your part for:
• Wall thickness and uniformity
• Draft angles and undercuts
• Material flow and gate locations
• Ejection feasibility
This helps ensure your design is optimized for reliable, cost-effective production.
American Tooling and Machining supports a variety of post-molding processes, including:
• Ultrasonic welding and mechanical assembly
• Surface finishing: texturing, polishing, silk-screening, laser marking
• Custom packaging and fulfillment
Let us know your end-use goals, and we’ll tailor the right services for your parts.
