Moulds & tooling

Tooling behind the pen.

Start with a proven structure.

For a logo or packaging update, an existing structure is the starting point. A new barrel or cap shape is reviewed separately for tooling, component fit and sampling.

  • Tip & reservoir fit

Production logic

Good OEM starts before mass production.

Product structure, ink, component fit, branding and packaging are confirmed before production so the factory is not solving basic design questions on the line.

01

Materials & components

Confirm the approved component and ink requirements.

02

Printing & preparation

Prepare branded parts and packaging against approved artwork.

03

Assembly

Controlled filling, tip / cap assembly and product finishing.

04

Inspection & packing

Check agreed appearance and functional requirements before shipment.

Bring your marker project to the factory.

Share the product, target market and customization requirements. We will confirm a suitable starting platform and sampling route.
