Series overview of our date stamps
Our series cover all applications – from classic date stamps to innovative marking stamps with functional properties.
Series DK / DA – Standard date stamp with height adjustment
The DK and DA series are classic date stamps with screwed-in setting insert and height adjustment. These date adjusters enable precise adjustment of the setting insert to the engraving and guarantee clean impressions in the component with simultaneously low acquisition costs.
Series DAP – Date stamp without height adjustment
In the DAP series, the setting inserts are screwed in without height adjustment. This version is ideally suited for tools for thin-walled molded parts and highest quality of the impression on the injection molding.
Series DAC – Date stamp without height adjustment for rubber injection molding
Thanks to the conical setting insert, we can guarantee high density of our date stamps.

Series DAR – Indexing stamp
The DAR series is our top technological product. The setting insert is screwed in without height adjustment and locks into 60 finely stepped positions. This makes the insert absolutely secure against rotation – even under high injection pressure. Here, the higher the injection pressure, the better the locking.
The DAR series patented by Walz Normalien® is the only date stamp on the market with this fine locking mechanism and guarantees maximum process reliability.
Series DAF, DARF and DAPF – Mountable from the mold side
All F series of our date stamps have a threaded pin on the back that can be reached with an Allen key when the setting insert is unscrewed from the inside of the date stamp. This allows these date indicators to be screwed in from the mold side.

Other designations for date stamps
Our date stamps belong to the group of identification standards and are often also referred to as date indicators, date adjusters, or identification stamps. They are an integral part of modern standard part systems for the highest quality requirements in tool and mold making.
