What We Do
Full-Service Plastic Manufacturing Capabilities
From rapid prototyping and in-house tooling through production molding and secondary services — Hope Plastics Co Inc delivers end-to-end plastic manufacturing under one roof. Every process is backed by our ISO 13485, AS9100D, and ISO 9001 certified quality management systems.
3D Printing / Rapid Prototyping
Accelerate your development cycle with FDM, SLA, and SLS rapid prototyping. Functional prototypes in days — validate designs, test fit and function, and move to tooling faster with fewer costly revisions.
- FDM, SLA & SLS technologies
- Functional prototypes in days
- Engineering-grade materials
- DFM analysis included
Mold / Tool Making
In-house mold design and tool building using CNC machining and EDM. Controlling tooling in-house means faster turnaround, lower cost, and direct engineering collaboration — from single-cavity prototype tools to multi-cavity production molds.
- CNC machining & EDM in-house
- Single to multi-cavity molds
- Prototype & production tooling
- Mold maintenance & repair
Injection Molding
High-precision thermoplastic injection molding for complex, tight-tolerance components. Wide range of engineering resins across a broad press tonnage range for prototype through high-volume production.
- 15 to 1,000+ ton press range
- Tolerances to ±0.001"
- Engineering & commodity resins
- Prototype to high-volume
Cleanroom Medical Molding
ISO 13485-certified cleanroom injection molding in a Class 10,000 (ISO 7) controlled environment for medical devices, surgical instruments, diagnostic components, and drug delivery parts.
- Class 10,000 (ISO 7) cleanroom
- ISO 13485 certified
- Full regulatory traceability
- FDA-compliant processes
Blow Molding
Extrusion and injection blow molding for hollow plastic parts — bottles, containers, fluid reservoirs, and custom industrial components with consistent wall thickness across a wide range of materials.
- Extrusion & injection blow molding
- Custom hollow components
- Wide material selection
- Industrial & consumer parts
Liquid Silicone Rubber Molding
Two-component LSR injection molding for flexible, biocompatible, and heat-resistant components. Ideal for medical seals, gaskets, overmolded grips, and high-performance parts requiring extreme temperature resistance.
- Two-component LSR molding
- Biocompatible grades available
- Overmolding capability
- Extreme temp resistance
Thermoforming
Vacuum and pressure thermoforming for large-format plastic parts, trays, enclosures, and packaging. Cost-effective tooling and fast lead times for low-to-medium volume production.
- Vacuum & pressure forming
- Large-format capability
- Low-cost tooling
- Custom trays & enclosures
Rotational Molding
Rotational molding for large, hollow, seamless plastic parts — tanks, enclosures, playground equipment, and industrial containers. Ideal for complex shapes that are difficult or costly to produce by other methods.
- Large hollow parts
- Seamless construction
- Complex geometries
- Tanks & enclosures
Beyond Molding
Secondary Services & Finishing
We offer a full suite of secondary services — assembly & kitting, pad printing, ultrasonic welding, hot stamping, heat staking, insert molding, overmolding, decorating & finishing, packaging, warehousing, and engineering support — so your parts arrive ready to use.
