What Are Plastic Injection Moulded Components?
Plastic injection moulded components are precision parts manufactured by injecting molten thermoplastic material into a precisely engineered steel mould cavity under high pressure — typically between 70 MPa and 200 MPa. Once the polymer fills the cavity and cools to a dimensionally stable state, the mould opens and the finished component is ejected, ready for use or further assembly.
The process is the world’s most widely used method for producing high-volume, complex-geometry plastic parts. It enables manufacturers to achieve tight dimensional tolerances (±0.05mm to ±0.1mm), excellent surface finishes, and consistent part-to-part repeatability — all at a low cost per unit at scale. This makes plastic injection moulding the manufacturing process of choice for automotive OEMs, electronics manufacturers, industrial equipment companies, medical device producers, and a broad range of other precision-demanding sectors.
Precision Moulding Services We Offer
As a vertically integrated plastic injection moulded components manufacturer and supplier, Multitek covers every moulding process variant your project may require.
1. Standard Plastic Injection Moulding
Our horizontal and vertical injection moulding machines produce complex thermoplastic components with consistent dimensional accuracy. We manufacture high-volume production parts in single and multi-cavity moulds with hot runner and cold runner systems depending on part geometry, material, and volume. This core capability covers part weights from 1 gram to 1,500 grams and clamping forces from 80 tonnes to 850 tonnes.
2. Insert Moulding
Multitek’s insert moulding capability encapsulates metal inserts — brass threaded inserts, steel dowel pins, copper electrical terminals, or filter meshes — within the plastic component during the moulding cycle. This creates a single integrated part that eliminates secondary assembly operations, reduces manufacturing cost, and improves pull-out resistance. Widely used in automotive connectors, electrical terminals, and industrial fasteners.
3. Overmoulding
Multitek’s overmoulding service combines two or more materials into a single component — typically a rigid engineering plastic substrate overmoulded with a TPE or TPU elastomer. Ideal for soft-touch ergonomic grips, waterproof sealed electronic housings, vibration-dampening mounts, and bi-material assemblies.
4. In-House Tooling & Mould Design
Our dedicated in-house tool room designs and manufactures precision injection moulds from P20 and H13 tool steel using CAD/CAM software, CNC machining, EDM wire cutting, surface grinding, and mould polishing. By keeping tooling in-house, Multitek maintains direct control over tool quality, modification timelines, and mould maintenance — enabling faster T1 sample delivery and better long-term mould life. Typical new mould lead time: 4 to 6 weeks.
5. Rapid Prototyping & T1 Sample Approval
Multitek supports concept-to-sample development through DFM review, gate location optimisation, and systematic T1 sample approval — accelerating product development cycles. First Article Inspection (FAI) reports are provided for all new tooling.
6. Sub-Assembly & Value-Added Services
Beyond moulding, Multitek provides complete in-house product assembly — mechanical assembly, ultrasonic welding, UV printing, labelling, kitting, and functional testing. This reduces your vendor count, simplifies supply chain management, and ensures quality is controlled within the same facility as moulding.
Our 7-Stage Plastic Injection Moulding Process
Multitek follows a structured, seven-stage manufacturing workflow from initial design review to final dispatch, ensuring quality, traceability, and on-time delivery at every stage.
1. Design Review & DFM Analysis
Our applications engineers review customer CAD files (STEP, IGES, SolidWorks) and apply Design for Manufacturability (DFM) principles — identifying draft angles, wall thickness uniformity, sink mark risks, gate locations, and parting line strategy. DFM feedback is provided within 5 business days. This stage prevents costly downstream changes and maximises mould life and part quality.
2. Mould Design & Tooling
In-house tool room engineers design precision injection moulds using CAD/CAM software, defining cavity and core geometry, cooling channel layout, ejection system, and gate type (edge, submarine, hot runner). Moulds are machined from P20 or H13 tool steel depending on production volume requirements. Typical new mould lead time: 4 to 6 weeks.
3. Material Selection & Validation
Multitek’s engineering team recommends the optimal thermoplastic resin based on your mechanical properties, operating temperature, chemical resistance, UL flammability rating, surface finish, and cost targets. All incoming resin batches undergo Melt Flow Index (MFI) testing and visual inspection against certificate of conformance before release to production.
4. T1 Sample Production & Approval
The first tool trial (T1) produces initial samples for dimensional inspection, visual assessment, and functional testing. All T1 dimensions are recorded on a First Article Inspection (FAI) report submitted to the customer for approval. Cavity-specific traceability is maintained throughout.
5. Mass Production with Process Controls
Once validated, production runs against a documented Control Plan specifying inspection frequency, critical dimensions, process parameters (barrel temperature, injection pressure, cooling time, cycle time), and operator instructions. Scientific moulding principles ensure process robustness. 24/7 production is available for high-volume programmes.
6. Quality Inspection & Testing
Each production batch undergoes dimensional checks using calibrated gauges, digital micrometers, and height gauges. Critical features are verified on our CMM (Coordinate Measuring Machine). Functional tests — pull-out force for insert moulded components, fit and assembly checks — are performed as specified in the control plan. 100% visual inspection is applied for cosmetic surface components.
7. Packaging, Labelling & Dispatch
Parts are packed to customer specification with batch labels carrying part number, revision, quantity, and date code. Dispatch documentation includes packing lists, certificates of conformance, inspection reports, and material test certificates. Export shipments include commercial invoices, packing declarations, and country-of-origin documentation.

Frequently Asked Questions
Q1 : What are plastic injection moulded components?
Plastic injection moulded components are precision parts manufactured by injecting molten thermoplastic material into a precision steel mould cavity under high pressure — typically 70 MPa to 200 MPa. Once cooled and solidified, the mould opens and ejects the finished part. The process enables high-volume production of complex geometries with tight dimensional tolerances (±0.05mm to ±0.1mm), excellent surface finish, and consistent part-to-part repeatability. It is the most widely used plastic manufacturing process globally.
