The manufacturing process begins with understanding the buyer’s product requirement. This includes the intended application, dimensions, material preference, colour, finish, quantity, packaging and delivery expectations.
Clear product information helps the manufacturer evaluate feasibility and prepare the design, quotation, tooling plan and estimated production schedule. Missing specifications can lead to incorrect assumptions and unnecessary design revisions.
- Product name, concept or category
- Intended product application
- Required dimensions and tolerances
- Material preference
- Colour and finish requirements
- Order quantity and packaging
- Destination country and delivery expectations
- Drawing, sample, 3D file or reference image, if available
CAD, or Computer-Aided Design, is used to create digital product drawings and three-dimensional models. CAD enables the manufacturer and buyer to review the product’s shape, dimensions, fitment, wall thickness and important features before mould development begins.
Small dimensional changes can affect fitment, strength, mould design and production output. The CAD stage provides an opportunity to identify and correct these issues before tooling costs are committed.
- Creates accurate digital product drawings
- Supports size, shape and feature planning
- Allows wall thickness and fitment to be reviewed
- Enables revisions before mould manufacturing
- Reduces misunderstanding between buyer and manufacturer
- Supports custom plastic product development
After the initial CAD model is prepared, the manufacturer reviews whether the product can be produced effectively through injection moulding. This is commonly known as a design-for-manufacturing or feasibility review.
The review may consider wall thickness, geometry, mould-opening direction, draft, material flow, expected shrinkage, strength and ease of removal from the mould. Proposed changes should be approved by the buyer before the design is released for tooling.
- Checks suitability for injection moulding
- Reviews wall thickness and product geometry
- Considers mould opening and product removal
- Assesses material flow and shrinkage
- Supports mould-planning decisions
- Helps reduce production risks before tooling
Once the product design is approved, mould design begins. The mould is the production tool that forms heated plastic into the required product shape. Mould design can include the cavity, core, runner system, gates, cooling channels, ejection arrangement and other tooling features.
CAD supports mould layout and technical design, while CAM helps prepare machining operations and toolpaths. Mould quality can affect product dimensions, surface finish, production speed and repeatability.
- Mould design follows the approved product drawing.
- CAD supports mould layout and technical planning.
- CAM supports machining and toolpath preparation.
- Gate, cooling and ejection requirements are considered.
- Mould design influences quality and repeatability.
- Tool planning is critical for bulk manufacturing.
After the mould design and machining plan are approved, CNC machines are used to manufacture mould components. CNC machining can create cavities, cores, inserts and other components according to the technical design.
Accurate machining supports better product fitment, dimensional control and repeatability. Additional tooling processes may be required depending on mould complexity, material, finish and design.
- CNC machines manufacture mould components.
- Cavities and cores follow the approved design.
- Accurate machining supports dimensional control.
- CNC processes reduce dependence on manual shaping.
- Tooling accuracy affects product finish and fitment.
- CNC mould development supports custom products.
After machining, the mould components are assembled and tested. Trial production is then conducted on an injection moulding machine to determine whether the mould and process produce the intended component.
Trial samples can be checked for dimensions, fitment, finish, material flow, shrinkage, warpage, colour and general usability. Mould corrections or process adjustments may be required before the product is approved for commercial production.
- The mould is assembled and tested.
- Trial production verifies the initial product output.
- Dimensions, fitment and finish are reviewed.
- Material flow, shrinkage and warpage are assessed.
- Corrections can be completed before mass production.
- Buyer sample approval should precede bulk production.
During injection moulding, plastic material is prepared, heated and injected into the mould cavity under controlled conditions. The material fills the mould, cools and solidifies into the required shape before the mould opens and the component is removed.
The process can be used for repeat production of construction safety products, industrial components, automobile-related parts, household products and custom plastic items.
- Plastic material is heated and injected into the mould.
- The component forms inside the mould cavity.
- Cooling solidifies the product.
- The mould opens and the component is removed.
- The cycle is repeated for the production quantity.
- Process controls support consistency across batches.
After production, components are inspected against the approved drawing, specification or reference sample. The inspection criteria depend on product application and may include dimensions, fitment, shape, colour, finish and visible moulding defects.
INNOVIS uses calibrated measuring instruments and quality-focused manufacturing practices to support consistency. Buyers should define tolerances, sampling requirements and acceptance criteria before production where these are relevant.
- Product dimensions are measured.
- Fitment and usability are reviewed.
- Colour and surface finish are inspected.
- Products are checked against approved specifications.
- Calibrated instruments support dimensional inspection.
- Final inspection helps reduce dispatch errors.
After inspection, accepted products are counted, finished where required, packed and prepared for dispatch. The packing format depends on the product, order quantity, destination, transportation method and buyer requirements.
International buyers should confirm inner packing, carton quantity, labels, barcodes, private branding, carton markings and export-packaging requirements before commercial production is completed.
- Accepted products are sorted and counted.
- Packing is selected according to the product and shipment.
- Carton quantity and dimensions are confirmed.
- Labelling and branding requirements are applied as agreed.
- Export packing should be discussed in advance.
- Dispatch planning supports coordinated delivery.
