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.

Small detail. Big difference.
We make the part nobody photographs and everybody depends on. A closure is a few grams of plastic that decides whether a product arrives intact — and that is a serious enough job to build a company around.

Engineered for a cleaner, safer world
NEWCAP is a specialised manufacturer of plastic closures and caps, based in the Eshtehard Industrial Estate. We supply factories in detergents, oils and lubricants, chemicals, adhesives and food with closures made for stable quality — precise, consistent and clean in finish — in bulk, and to specification when a product needs something of its own.

What we stand for
Tolerances are the product
A closure that is nearly right is wrong. We work for a seal that repeats from one closure, and one batch, to the next.
Solve it at the drawing
Most failures on a filling line were decided months earlier in a 3D model. We would rather spend the time there.
Say it, then do it
Quantities, dates and specifications are commitments. When something changes, you hear it from us first.
Less material, longer life
Lighter parts, recyclable single-material designs and closures that keep a product usable to the last dose.
Precision in people
Tooling and machines matter less than the hands that set them. We invest in the team that runs them.
Stronger partnerships
The best projects start before the specification is finished, when there is still room to change the answer.
