From concept to production
Custom closures, made to your specification
Bring us your product and its container. We review the specification and produce a closure that fits — in the size, material and colour your product needs, and in the quantity your line runs at.
Our capabilitiesQuality in every detail
Built on quality
Precise, uniform and clean in finish. Every closure is made for a stable, repeatable quality your production can rely on.
- Dimensional precision
- Uniform batches
- Leak-free sealing
- Clean visual finish
Colour to specification
One closure.
Your colour.
Every closure is produced in the colour your product calls for — to match your brand, or to tell one product line from the next at a glance.
Six of many — any colour to order.

One cap. Many industries.
A closure is judged by what sits underneath it. Each sector we supply asks something different of the same small part — and that is what shapes the design.

Household, laundry and cleaning
Thick, surfactant-heavy liquids that creep, foam and attack weak materials. The closure has to open easily in a wet hand and still seal after twenty cycles.
- Surfactant resistance
- Measuring caps
- Wet-grip ribbing
- Tamper evidence

Engine oil, brake fluid and lubricants
Oils creep through any gap, and brake fluid attacks weak materials and draws moisture from the air. The closure has to seal tightly and consistently, because a leaking bottle on a shelf or in a workshop is both a loss and a hazard.
- Leak-free sealing
- Brake-fluid caps
- Moisture protection
- Custom colours

Industrial chemicals, glues and adhesives
Aggressive contents, and products that cure on contact with air. The closure has to resist the chemistry, keep air out so an adhesive does not harden in its container, and stay safe wherever children could reach it.
- Chemical resistance
- Airtight sealing
- Child-resistant caps
- Adhesive container bases

Food products and industrial packaging
From food containers to 20-litre gallons, the closure has to be hygienic, consistent from one batch to the next, and show clearly whether the pack has been opened.
- Hygienic design
- Gallon caps
- Tamper-evident bands
- Batch consistency
How we work with you
Understand the contents
Chemistry, viscosity, storage life and filling temperature — before any geometry is discussed.
Match the line
Capping torque, head speed and container tolerance decide what the closure can be.
Prove it, then scale
Samples and validation runs first; continuous production only once the seal is proven.
