Direct Part Marking
RNJet 100 / 200
Piezo marking directly on metal brackets, housings and plastic parts — up to 15 mm print distance, up to 36 mm tall.
View Full SpecsCoding & Marking on Automotive Parts
Durable, high-speed marking for filters, brake components, metal and plastic parts, rubber hoses and the packaging they ship in — with serialization and GS1 DataMatrix support for traceability.
Automotive Parts Manufacturing
Durable codes on demanding automotive substrates
Automotive suppliers mark dozens of part numbers a day across metal brackets, plastic housings, rubber hoses, filters and brake components — often on oily, curved or textured surfaces moving at production speed. Codes need to survive handling, cleaning fluids and heat, while still matching the lot numbers, date codes and serial numbers your customers and auditors expect.
RNJet thermal inkjet (TIJ) and piezo printers mark directly on parts and their packaging, printing static text, auto date & time, batch numbers, serial numbers, barcodes and GS1 DataMatrix — without the daily cleaning and makeup fluid that continuous inkjet (CIJ) printers require.

Automotive Coding & Marking FAQ
Oil and air filters, brake components, rubber hoses and tubing, metal brackets and housings, plastic parts, and the cartons, cases and pallets those parts ship in.
Yes. RNJet printers support auto-incrementing serial numbers, lot and batch codes, date codes, barcodes and GS1 DataMatrix — the code types automotive suppliers use to meet customer traceability requirements such as IATF 16949.
With the right ink formulation, RNJet printers mark on metal, plastic, rubber and coated surfaces — including curved and uneven parts, at up to 15 mm print distance on piezo models.
RNJet thermal inkjet and piezo printers avoid the daily cleaning, makeup fluid and nozzle maintenance that CIJ printers require, while printing comparable or higher-resolution codes at up to 180 m/min.
Yes. RNJet printers mount directly on new or existing lines, print from the side, downwards, upwards or at an angle, and trigger from a photo-eye or PLC signal without slowing the line.
