Client: Wyma Engineering (Canterbury, New Zealand)
Manufacturing Partner: The Composite Group (Christchurch, New Zealand)
Overview
Wyma Engineering required food-grade, easy-to-clean components for a commercial vegetable polisher used in produce processing environments. The machine operates in wet, high-throughput conditions where hygiene, durability, and washdown efficiency are critical.
Wyma engaged The Composite Group to design and manufacture the moulds and then produce the finished fibreglass articles for the machine. The project required close collaboration to ensure compliance, cleanability, and repeatable production quality.

The Challenge
- Design smooth, non-porous surfaces for fast and effective cleaning
- Meet strict hygiene requirements
- Ensure durability under frequent washdowns and chemical exposure
- Deliver production-ready moulds for consistent, scalable manufacturing
- Produce a cosmetically appealing product, that suited the high-end machine that the fibreglass parts were being fitted to.
The Solution
The Composite Group worked alongside Wyma’s engineering team from early design through to production.
- Custom fibreglass moulds were designed with smooth radii, minimal joins, and integrated drainage to eliminate dirt traps.
- Superior resins and gelcoats were selected to meet hygiene and safety requirements and create seamless, non-porous surfaces.
- Moulds were engineered for long-term durability, ensuring consistent surface finish across production runs.
- Finished fibreglass components were manufactured in-house and supplied ready for integration into the final machine assembly.


The Result
- Improved cleanability: Seamless surfaces reduced cleaning time and downtime.
- Aesthetic Integration: Smooth Fibreglass Materials combining with industrial metal to complete the high-end look of this high quality machinery.
- Operational durability: Components perform reliably in demanding processing environments.
- Scalable production: Robust moulds enable consistent, cost-effective manufacturing. These moulds are ready and able to be used to produce an article anytime Wyma require new parts for a new machine build.
This project demonstrates The Composite Group’s capability in developing and delivering high quality, easy-to-clean fibreglass solutions for advanced food-processing machinery.
