Comprehensive Injection Moulding Solutions — From Concept to Finished Product
At W&S Plastics, we specialise in delivering end‑to‑end plastic injection moulding solutions for medical, electronics, industrial and consumer applications. With facilities in Australia and Malaysia, advanced ISO‑certified systems, and deep scientific‑moulding expertise, we support your project from early concept through to mass‑production assembly and packaging.
Our strength lies in precision, repeatability, and quality — every step of the way.
Product Design & Engineering
We help turn ideas into production‑ready components using structured design workflows and industry-leading tools. From the first sketch or CAD file, our engineers collaborate with you to optimise manufacturability, functionality, and cost.
What we provide:
- 3D CAD modelling and fully toleranced 2D control drawings
- Guidance on material selection, tooling considerations, and manufacturability
- Engineering support grounded in ISO 13485, ISO 9001 and ISO 14001 certified systems
- Project management tools to ensure nothing is missed — ideal for multi‑tool programs
Whether you are refining your design or building from scratch, our engineering team ensures a smooth path to tooling and production.
Tooling & Toolmaking
Precision tooling is the foundation of consistent moulded parts. We work closely with trusted toolmakers in Australia and Asia and maintain in house tool rooms in both facilities to support modifications, repairs, and maintenance efficiently.
Our tooling capabilities include:
• Prototype tools for small validation runs or early market trials
• High volume production tools with long life warranties
• Advice on steel grades, cavity numbers, cooling design and lifetime performance
• In house tool rooms for quick, low cost modifications and repairs (as detailed in facility info)
Our priority is ensuring every mould is built to the highest standard and operates correctly over its entire lifecycle.
Validation & Quality Assurance
Quality is not an afterthought — it is built into every stage of our process.
We tailor validation to your exact requirements, whether for a simple component or a regulated Class I/II medical device.
Our validation services include:
• Dimensional checks and mating component fit testing for simple parts
• Full specification conformance reports
• Capability analysis (Cp, Cpk) and mechanical testing
• Scientific moulding studies to establish stable, repeatable process windows, rather than “tuning” settings shift-by-shift
• ISO 13485 aligned process documentation and traceability (supported by site wide certifications
This ensures consistent part quality, validated performance, and regulatory compliance.
Injection Moulding & Scientific Moulding
Injection moulding is at the core of our business. With modern European machinery across two countries, we mould components with exceptional accuracy and repeatability.
Our equipment and capabilities include:
• Machines from 20–700T in Sydney and 80–350T in Johor, Malaysia
• 2K/Multicomponent moulding (Arburg co moulding capability)
• IQ Weight Control for automatic shot weight optimisation as conditions vary
• IQ Clamp Control for stable clamping force and reduced risk of flash
• Servo-driven systems that improve energy efficiency and accuracy
• Experience in overmoulding, insert moulding and multi shot production
Every moulded component is produced using scientifically derived process settings to ensure accuracy, stability, and long-term repeatability.
Cleanroom Moulding & Medical Manufacturing
We specialise in medical grade components under certified quality systems.
Cleanroom capabilities:
• ISO Class 7 cleanroom and ISO 7 moulding cell in Sydney
• ISO Class 8 cleanroom for the entire production area in Johor, Malaysia — ideal for medical and electronic components
• Bio controlled environments in Sydney
These facilities support sterile medical device manufacturing, sensitive electronics, diagnostics products, and other contamination critical parts.
Secondary Operations & Assembly Services
We deliver more than moulding. Our downstream services allow you to consolidate suppliers and streamline your supply chain.
Services include:
• Printing (pad, digital, screen)
• Welding (ultrasonic, heat staking, laser where applicable)
• Mechanical assembly and sub assemblies
• Functional testing, inspection and packaging
• Global component sourcing to integrate purchased parts with moulded components
These capabilities let us ship your product in a ready to use or ready to sell state.
Supply Chain Management & Global Support
With facilities in Australia and Malaysia and experience supporting world leading medical device manufacturers, we manage complex supply chains with transparency and reliability.
Strengths include:
• Real time production monitoring via MES systems
• Dual site redundancy for risk mitigation and continuity of supply
• Cost effective production options without compromising quality
• Seamless coordination of multi cavity tools, validation, logistics, and assembly flows
We support OEMs from prototype volumes right through to multi-million-unit annual programs.
