How our custom plastic manufacturing process works
As a custom plastic moulding company, Whurl Plastics manages the full production process for custom plastic components, from planning through to finished supply
Order size does not dictate the level of care or the process. Whether you need 2,000 units in a single colour or a larger production run, each project is clearly mapped out from concept and CAD modelling through to tooling, prototyping, production and packing.
Traceability is built in down to batch level, and small orders follow the same documentation and quality checks as larger runs. Machines operate 24/7, so urgent jobs can be scheduled when priorities change, rather than being pushed to the back of the queue.
Colour matching is routine, whether the product needs to match a precise shade or stand out. Pigments are sourced globally, including specialist options such as fluoro or gold. Recyclable or bio-based plastics can also be considered where sustainability is a priority.
From sketch to finished part, every step is set out so you know what comes next. In-process checks throughout each run help prevent wasted time and costly errors, and each batch is packed ready for your next stage.

- Reground plastic reuse and recyclable or bio-based resin options
- Part assembly, labels, and packing arranged for direct shipment
Design and tooling from any starting point
A conversation, photo, rough sketch, or existing sample is enough to get the process underway. CAD design is developed with your input, with practical checks along the way to make sure the part works as intended in real-world use, not just on screen.
As the design develops, adjustments can be made to improve fit, practicality, durability, or production efficiency. You stay involved throughout, with ongoing feedback helping refine the product for your application.
Tooling options are sourced through local and overseas manufacturers, giving you flexibility around cost, lead times and project requirements. These options are discussed early, so expectations are clear before production begins.
Tooling is matched to the scale of your project and the demands of the product, helping keep investment aligned with your production needs. More detail is available under plastic product design and development.

Short-run and flexible custom plastic components manufacturing
Machines run around the clock, keeping scheduling flexible as orders change. Short runs from 2,000 units per colour are standard alongside larger batches, so there is no need to commit to container loads just to get started.
Where feasible, schedules can be adjusted when urgent changes arise.
Production covers small runs for new launches or limited batches, larger ongoing runs for steady supply and multi-colour or multi-variant manufacturing to support a full product line. Before full production begins, prototypes are made and checked for your sign-off.
Pigments are sourced internationally, so options are not limited to local availability. If your project requires plastic injection moulding or custom plastic manufacturing, both can be scoped.

Quality and traceability in every batch
Quality checks are built into production, not treated as a final step. Batches are inspected at set intervals to identify issues early and reduce the risk of rework or delays.
QR codes and batch tracking can be added to packaging and paperwork, making it easier to trace parts if a query arises. Every order is logged and batch coded for your records, with traceability supported by the QR codes and batch numbers.
Samples and supporting documents can also be provided for review or compliance when required.
For food-grade or regulated work, Food Grade Plastic Manufacturing and clean room production follow strict cleaning practices and external testing. Test reports are available if needed, and food-grade production tracks the full supply chain, not just the resin.

Manufacturing for the long haul with less waste
Plastic offcuts and scrap are reground and reused where practical, reducing waste and helping to control costs. Where suitable, recyclable or bio-based plastics can also be considered, including sugarcane resin options.
Packaging boxes can be reused up to ten times to reduce packaging waste and cost.
Additional finishing services include the assembly of parts such as straws, rings or sponges, the application of stickers or labels for branding or compliance, and packing for direct shipment so products arrive ready for the next step.
Orders leave the factory packed for their next destination, whether that is your production line, warehouse or customer.
Manufacturing is built around the steps that matter: injection moulding, concept development, tooling, prototyping, production and packing, with traceability and cost control built in for customers in New Zealand and across Australasia.

Send drawings, a sample or a clear description with intended volume and material preference. Quotes can cover tooling, resin, cycle time, finishing and packing. Early design checks help flag issues before numbers are confirmed.
Function, end use, target look, annual quantity, inserts, threads, colour and compliance needs all guide the design. CAD files and notes on real-world use help reduce problems later.
Short runs can start from 2,000 units, with tooling and planning set up to handle higher volumes if demand grows. Lead times, stock holding and process controls can be discussed against your schedule.
From the first batch, raw materials and production steps are logged. Regular checks, samples and records make it easier to trace and correct issues if they appear.
Start with how the part is used, then check if recycled or bio-based plastics suit the application. Strength, chemical resistance, temperature, colour and environmental targets all matter. Recommendations come from supplier information and testing.
