Custom Injection Molding Solutions – Unlocking Versatility
We offer a full range of advanced injection molding techniques—designed to match diverse product requirements and industry demands.
Insert Molding (Embedded Metal or Ceramic Components)
Process: Pre-place metal, ceramic or pre-formed inserts into the mould, then inject plastic to fully encase and integrate them into one component.
Advantages:
• Combines metal strength and plastic light-weight as a unified part.
• Reduces or eliminates subsequent assembly steps, lowering production cost and simplifying logistics.
• Ensures the insert is captive and immovable within the plastic – preventing loosening or detachment.
Applications:
Metal-threaded fasteners, sensor housings, surgical-instrument handles, tool grips, and multi-material devices.
Two-Colour / Multi-Colour Molding
Process: Employ two (or more) injection units and a specially engineered mould to combine different colours or different materials in one shot.
Advantages:
• Distinctive aesthetics: seamless colour blends or patterns improve product premium feel.
• Functional upgrades: soft-touch zones (TPE/TPU) adjacent to hard plastic bodies.
• One-step manufacture: no glue or separate assembly steps between colours.
Applications:
Multi-colour toothbrush handles, soft-touch electronic casings, automotive interior accents, stylish consumer devices.
Microcellular Foam Molding
Process: Inject a super-critical fluid (such as nitrogen) along with the polymer, creating an internal micro-cell foam structure inside the plastic.
Advantages:
• Lightweight. Reduces part mass while maintaining rigidity.
• Low internal stress → dimensional stability and reduced warpage.
• Saves material usage, cutting cost.
Applications:
Large thick-walled structural parts, aerospace or automotive components requiring strict dimensional consistency, other lightweight design parts.
High-Speed Thin-Wall Injection Molding
Process: Utilise high injection speed and pressure to mould extremely thin wall sections (often < 0.5 mm).
Advantages:
• Ultra-lightweight parts.
• Very short cycle times = high throughput.
• Material usage minimised.
Applications:
Food packaging trays, ultra-thin smartphone back covers, precision electronics trays, disposable medical devices.

Advantages & Challenges of Injection Molding — Clear Guidance to Decide
Core Advantages
• High efficiency and low unit cost: Once the mould is developed, cycles can run in seconds, enabling large-scale production at low cost per piece.
• High repeatability and precision: Mould ensures every part is consistent in shape and dimension.
• Wide material and function variety: From commodity resins to high-performance engineering plastics.
• Complex geometry in one shot: Enables reduction of assembly steps and integrated part design.
Common Challenges
• High initial investment: Mould design and tooling cost can be substantial upfront.
Our solution: Offer cost-optimised tooling and small-batch options.
• Not economical for very low volumes: For tens or hundreds of parts, the per-unit cost may be high.Guideline: Best suited for ≥ 1,000 pieces.
• Design flexibility constraints after mould creation: Changes post-moulding incur cost and time.
Recommendation: Engage in design for manufacturability (DFM) early.
Should You Use Injection Molding for Your Project?
Ask These Three Questions
1. Production Quantity
Do you require thousands of parts rather than just dozens? If yes → injection molding is cost-effective. If only prototyping or very low volume, consider alternatives (3D-printing, CNC).
2. Part Complexity & Consistency
Does your design require high precision, tight tolerances, multiple assemblies or complex geometry? If yes → injection moulding is highly suitable. If simple and tolerant, simpler methods may suffice.
3. Budget & Investment Willingness
Do you have upfront budget to invest in tooling with the goal of long-term, high-volume savings? If yes → injection moulding makes sense. If budget is extremely limited for tooling and only very low volume is required → reconsider.
