FEATURES Strengths of our Mark Tubes and Display Products
Clear, indelible engraving
By stamping on non-marking tubes (those without product names or specifications printed), the engraving stands out clearly. We achieve high-quality printing that is not easily erased.
Selectable shapes such as round and oval
General-purpose round (MTB), oval (MCR), and halogen-free (ETCM) types allow selection of shapes and materials according to application and wire diameter. Oval types have strong rebound properties, effective in preventing displacement in movable and vibrating parts.
Non-shrinkable, also provides insulation protection
Mark tubes are non-shrinkable, simultaneously providing insulation protection and identification for wires. One product fulfills two roles, contributing to reduced man-hours.
Custom characters and large project support
We also support special characters such as hiragana, katakana, and logos. We can also handle custom production for large projects with small quantities of various prints, long character strings, and large diameter sizes. Please consult us first.
