Developing a plastic product is a strategic process that requires precision, planning, and expert execution. Whether you’re in automotive, consumer goods, medical, electronics, or packaging, you need a reliable partner to turn your concept into reality.
At UGP Plastics, based in Canada, we offer custom plastic injection molding backed by expert mold design, short-run plastic production, and full-service project management. In this guide, we outline the full plastic injection molding product development process—so you understand how it works and why UGP Plastics is your trusted partner.
Step 1: Concept Discussion & Requirement Analysis
Every successful product begins with a solid foundation. Our process starts with a detailed consultation to understand your vision and functional goals.
This includes:
-
Application Assessment: We assess the end-use, environment, and performance criteria—structural strength, chemical resistance, or aesthetics.
-
Material Consideration: We help you choose from plastics like ABS, polycarbonate, or nylon, depending on thermal, mechanical, and regulatory needs.
-
Volume Estimation: Whether you need short-run injection molding parts or high-volume production, we help balance cost and scale.
Step 2: Molding Design & Engineering Feasibility
Once goals are clear, our engineering team moves into design and feasibility analysis.
Key highlights:
-
Design for Manufacturability (DFM): Optimizing features like wall thickness, draft angles, and undercuts to prevent defects and waste.
-
Injection Mold Design Simulation: Simulates plastic flow to pre-empt issues like shrinkage or warping.
-
Material Compatibility: We verify that your material meets strength, flexibility, and durability requirements.
This step ensures that your design is both manufacturable and optimized for performance and efficiency.
Step 3: Prototyping & Pre-Production Testing
Before building the mold, we offer rapid prototyping to visualize and validate the part.
Why prototyping matters:
- Test and revise designs quickly.
- Identify flaws before investing in tooling.
- Present tangible parts to stakeholders or investors.
We offer 3D printed, CNC-machined, or soft-tool molded prototypes, depending on your needs and timeline.
Step 4: Mold Design & Fabrication
Your approved design moves into the tooling phase. We create a high-performance mold that can withstand the pressures of custom plastic injection molding.
This phase includes:
-
Custom Mold Engineering: From multi-cavity systems to hot or cold runners, tailored to your part’s needs.
-
Insert Molding Tooling: Supports parts requiring embedded metal, sensors, or electronic elements.
-
Fast Turnaround: In-house tooling and project management help meet tight deadlines.
Step 5: Injection Molding Production
This is where your product is molded into physical form.
Our services cover:
-
Short-Run Injection Molding: Ideal for small batches, market testing, or pilot projects.
-
High-Volume Injection Molding: For consistent large-scale production with tight tolerances.
-
Insert Molding Capabilities: Integrate fasteners, magnets, or circuits during molding.
During this stage, molten plastic is injected into the mold, cooled, and ejected as a final part—ready for use or assembly.
Step 6: Quality Control & Compliance Testing
We maintain strict quality assurance to ensure every molded part meets expectations and regulatory standards.
Our QC methods include:
- Dimensional Tolerancing: CMMs and calipers to verify specifications.
- Surface & Structural Checks: Ensuring consistent texture and finish.
- Functionality Testing: For parts exposed to load, movement, or pressure.
We follow ISO and industry-specific protocols for automotive, medical, and technical parts.
Step 7: Packaging, Fulfillment & Support
We don’t stop at manufacturing. Our post-production services include:
- Custom Packaging: Bulk, individually bagged, or kitted solutions with labeling.
- Logistics & Delivery: Fast fulfillment across Canada and export-ready shipping.
- Tool Maintenance & Storage: We store and maintain molds for future production runs.

Key Considerations for Plastic Product Development
To streamline product development, consider these critical factors:
-
Material Selection is Crucial:The right material affects performance, compliance, and durability. For example, nylon plastics offer excellent strength and chemical resistance—but selecting the right type of nylon is key.
Tips:
- Consider heat, moisture, and chemical exposure.
- Match tensile strength and impact resistance to function.
- Ensure regulatory compliance (e.g., food-grade, medical).
-
-
Integrating Plastic Overmolding for Enhanced Design: Plastic overmolding combines materials into a single part—adding grip, sealing, or protection. It’s ideal for injection molded plastic components that require ergonomics or embedded elements.
-
Benefits include:
-
- Soft-touch grip
- Protection for circuits/sensors
- Merging of material properties
-
Avoiding Defects Like Flow Lines or Flash:Visual or structural flaws like flow lines or flash can result from poor mold design or material behavior.
Prevention includes:
- Adjusting injection speed and pressure
- Proper mold venting
- Strong mold clamping and parting line design
