In the fast-moving world of agriculture, time and precision are everything. When you're developing a new product - whether it's a nozzle, a valve, or a housing for electronics -The Plastic injection moulding process from concept to field must be both fast and flawless. That's why more agricultural OEMs are choosing injection moulding backed by simulation, prototyping and in-house tooling.
This blog walks you through the complete journey of how an idea becomes a high-performance plastic component in the field - engineered for the realities of farming.
Step 1: Design Begins with the End in Mind
Everything starts with a CAD model of the component. But for Plastic-IT, this isn't just a drawing - it's the foundation of a simulation-led development process.
- Tools that evaluate wall thickness, stress points and undercuts.
- We assess the agricultural environment (UV, water, impact, chemicals).
- Materials are selected using real-world performance modelling.
- Parts are evaluated for Design for Manufacturability (DFM).
Step 2: Virtual Simulation Before Any Plastic is Moulded
Next comes the power of Moldflow simulation, where we:
- Analyse flow paths to avoid defects like weld lines or voids.
- Evaluate cooling and shrinkage to maintain dimensional accuracy.
- Validate the part's ability to withstand field stress.
- Optimise gating and ejection strategies.
Moreover, this means fewer tooling revisions, shorter development time and reliable parts from the first run.
Step 3: Prototyping - Fast, Accurate and Testable
With a simulation-approved design, we move into prototyping:
- 3D-printed or machined prototypes.
- Early-stage field testing for fit and performance.
- Refined designs based on testing feedback.
- Optional short-run soft tooling for functional trials.
Therefore, our prototyping allows agri engineers to see, feel and test the part before investing in full-scale tooling.
Step 4: Tooling and Production
Once approved, tooling begins:
- High-quality steel or aluminium moulds built in-house.
- Mold tools engineered for production volume and material type.
- Trial runs followed by dimensional inspection and tweaks.
- Full-scale production starts with final approval.
Also, our in-house capabilities reduce delays and ensure consistency across thousands of components.
Step 5: Final Touches and Field Deployment
Beyond moulding, we offer:
- Secondary operations (e.g. ultrasonic welding, overmoulding, part assembly).
- Part traceability and quality certification.
- Packaged delivery ready for OEM integration or distributor logistics.
Your component arrives not just finished - but field-ready.
Why Agri OEMs Trust Plastic-IT
Agricultural product designers choose Plastic-IT because we offer:
- Deep sector knowledge of farming applications.
- Materials expertise tailored to field conditions.
- Simulation-led workflows for design confidence.
- Complete in-house production: design > tooling > delivery.
We don't just build moulds - we engineer field-ready solutions that last.
FAQs
1. How long does the full injection moulding process take?
From CAD submission to first production parts, the timeline is typically 4-8 weeks depending on part complexity and prototyping needs.
2. Can I test the part before committing to full tooling?
Yes - prototyping options include 3D prints and soft tools for low-volume test runs.
3. What simulation tools do you use?
We use Moldflow to simulate fill, pack, cooling and warp before production. It is a process simulation, so it tells you how the part will mould rather than how it will survive in a field. Structural and in-service performance is FEA, which is a separate exercise and we will say so rather than blur the two.
4. Can you handle both design and manufacturing?
Absolutely. We provide full-service support from CAD evaluation to tooling, production and finishing.
5. What's the benefit of in-house tooling vs third-party?
Faster lead times, better communication and complete control over quality and revisions - ideal for agricultural applications with seasonal deadlines.
