Injection Molding & Tooling Services
High-quality custom injection molds and precision plastic parts, from rapid tooling and functional prototypes to low-volume and production runs, backed by 19+ years of manufacturing experience, tight-tolerance mold designs, overmolding and insert molding capabilities, and personalized engineering support with reliable quality and clear communication.
What is Injection Molding?
Injection molding is a highly efficient manufacturing process in which molten plastic material is injected under high pressure into a precision-engineered mold cavity. Once the material cools and solidifies, the finished part is ejected, delivering consistent, high-quality components with excellent repeatability.
This process excels at producing complex geometries, tight tolerances, and superior surface finishes at scale. It is widely used for both functional prototypes and end-use production parts across industries such as medical devices, automotive, electronics, consumer goods, and industrial equipment.
At Imago, we combine advanced tooling capabilities with deep process knowledge to deliver reliable injection molded parts tailored to your specific requirements.
Injection Mold Tooling
We design and manufacture high-quality injection molds engineered for your part geometry, material selection, production volume, and budget. Our experienced tooling team focuses on optimizing cycle time, part quality, and long-term mold durability.
Mold Types We Offer
Rapid / Prototype Tooling
Aluminum or soft steel tooling ideal for functional testing and low-volume production.
Production Tooling
Hardened tool steels such as P20, H13, S136, NAK80 and other grades designed for medium to high-volume runs with excellent longevity.
Key Tooling Capabilities
Mold cavity tolerances as tight as ±0.02 mm
Single-cavity, multi-cavity, and family mold configurations
Expert manual DFM review and process optimization
Optimized cooling channels, gate design, venting, and ejection systems
Lead times typically ranging from 7 to 18 days depending on mold complexity and class
Steel vs. Aluminum Molds
Tooling Materials
We select mold materials based on your production requirements:
Aluminum (6061, 7075)
Excellent for prototypes and low-volume production, offering fast machining and cost-effective tooling.
Tool Steel
P20, H13, S136, NAK80, 718H, and other grades ideal for medium to high-volume production with superior wear resistance and dimensional stability.
Our team works closely with you to recommend the most suitable tooling solution that balances upfront investment, lead time, and total cost of ownership.
Our Injection Molding Services
Custom Injection Molding
We provide high-quality custom injection molding for a wide range of part sizes and complexities. Whether you need functional prototypes or production parts, we deliver consistent quality with excellent surface finish and dimensional accuracy.
Low-Volume Injection Molding
Low-volume injection molding is ideal for prototypes, market validation, pilot runs, and bridge production (typically 100 to 10,000 parts). By using rapid tooling with aluminum or soft steel molds, we significantly reduce upfront tooling costs and lead times compared to traditional high-volume steel molds.
Key Benefits:
Lower initial investment and faster time-to-market
No minimum order quantity — flexible for testing and small batches
Easy design modifications during early stages
Scalable production — start with single-cavity tooling and upgrade as demand grows
Production-grade parts suitable for functional testing and early sales
Overmolding
Overmolding is an advanced technique that bonds two or more materials — typically a rigid substrate with a soft elastomer or a second plastic — into a single, unified component during the molding process.
Key Benefits:
Eliminates secondary assembly steps and reduces overall production cost
Improves ergonomics, grip, shock absorption, and sealing performance
Enhances product aesthetics and perceived quality
Creates strong, permanent bonds between materials
Common applications include medical device handles, power tools, consumer electronics grips, automotive components, and household products.
Insert Molding
Insert molding encapsulates pre-placed inserts (metal, plastic, ceramic, or electronic components) directly into the plastic part during the injection process. This creates a strong, integrated assembly without the need for secondary fastening or assembly operations.
Key Benefits:
Eliminates assembly steps and reduces part count
Increases overall part strength and durability
Reduces part size and weight compared to traditional assembly methods
Ideal for threaded inserts, electrical contacts, structural reinforcements, and hybrid components
Materials for Injection Molding
We work with a wide range of thermoplastic and thermoset materials to meet diverse functional, aesthetic, and regulatory requirements. Our engineering team helps you select the most suitable material based on mechanical properties, chemical resistance, temperature performance, appearance, and cost.
Common Materials Include:
Commodity Plastics
ABS, PP, PE, PS, HIPS
Engineering Plastics
