Products and equipment for rubber stamp making

Objet d'un brevet international, le flan est une plaque thermodurcissable semi polymérisée assurant, après ramollissement, la prise d'empreinte de caractères plomb, magnesium ou clichés photopolymères et permettant, après cuisson donc durcissement, l'obtention d'une matrice en creux dans laquelle sera moulé le caoutchouc :


disponible

soit en format A 4 (315 x 235 mm), en cartons de 20, 50 ou 100 plaques

soit en format 650 x 500 mm , en cartons de 10, 20 ou 25 plaques


Epaisseurs standards : Epaisseur 4 mm ou 5 mm
Autres épaisseurs réalisables : 6, 7, 8 et 9 mm pour moulage de photopolymères , clichés magnesium ou zinc.

Le film lumière du jour est un film photosensible réagissant aux Uvs, permettant de produire le film négatif à travers un film positif (calque) imprimé sur une imprimante jet d'encre ou laser.

Le négatif s'insole dans la machine photopolymère Thermogravor et se développe (révélateur) et se fixe (fixateur) en cuvettes.

Les films positifs et lumières du jour sont disponibles en format A4 par paquet de 100.

Le photopolymère dur est une plaque photosensible en relief assurant, par un moulage en pression, la réalisation de la matrice dans le flan.

Il est obtenu par une insolation  aux UV à travers un négatif. Les parties exposées aux UVs résistent au développement sous l'eau et produisent le relief de la plaque. Les parties non exposées sont éliminées par brossage. 

L'épaisseur de ce relief donne la hauteur future des caractères de vos tampons.

Epaisseurs 1.52 et 1.75 mm développable à l'eau.

Format A4 par 20 plaques.

La plaque photopolymère en relief va être moulée dans le flan de clicherie pour une obtenir la matrice (moule) en creux.

Le moulage se fait dans une presse à empreindre format A4 ou A5. Le flan est ramolli à haute température et le polymère est rentré en pression dans le flan.

Après cuisson la matrice (moule en creux) est obtenue pour le moulage du caoutchouc.

 

Le caoutchouc non vulcanisé est disponible sous forme de rouleau, en plusieurs coloris.

La feuille de caoutchouc est disposée sur la matrice et l'ensemble est moulé en pression dans une presse à vulcaniser (identique à l'étape précédente). Le caoutchouc est vulcanisé (cuit) dans la matrice.

Après cuisson la feuille de caoutchouc est découpée pour obtenir les tampons qui seront montés sur des montures bois ou automatiques.

Materials and supplies needed

Thermogravor photopolymer processing machine

A 4 size photopolymer processing machine 

Designed and manufactured by our company, to produce photopolymer stamps from liquid resin or hard photopolymer plates to be pressed into a matrix board (mold) 

The machine is made of 3  parts : 

Exposure part  (to expose photopolymer material to UV light)

  • UV tubes with on/off digital timer including memory 
  • vacuum pump to keep  positive and negative films or negative  film and  photopolymer plate  in close contact
  • glasses  with closing and calibrating system for liquid photoplymer material processing
  • plastic tray with holding system, for liquid resin post exposure
  • compressor to pierce air bubbles in liquid resin

Engraving part : (to develop (wash out) photopolymer material

  •  all pieces are in stainless steel
  •  thermostat for water temperature control
  •  timer to start the engraving unit
  •  the engraving mechanism is outside water to avoid dirt and jamming problems of the  moving part                               

Drying part (to harden photopolymer material)

  • 3 drying compartments
  • temperature control by thermostat
  • on/off timer         
  • 3 drying compartments

PEVP A5 Moulding and Vulcanizing Press

Moulding and vulcanizing press to press characters into a matrix board and get a mold in which rubber/ ink is molded

  • Size A5 (270 x 230 mm)
  • Hydraulic pressure provided by  coupled hydraulic jack and pump
  • 2 PID electronic controllers  securing  perfect  accuracy and distribution  of temperature  for  pre-inked and rubber stamp making
  • Manual digital timer for control of processing times.

PEVP A4 Moulding and Vulcanizing Press

Moulding and vulcanizing press to press characters into a matrix board and get a mold in which rubber/ ink is molded

  • Size  A4 (350 x 300 mm)
  • pressure is provided by separate pump and jack
  • 2 PID electronic controllers secure perfect accuracy and distribution of temperature for pre-inked and rubber stamp making
  • Manual digital timer for cycle control
  • Manometer for pressure control

Automatic Moulding and Vulcanizing Press

Motorized moulding and vulcanizing press, size 350 x 300 mm, for rubber and pre-inked stamp making.

All manufacturing steps are automatically performed . It is just necessary to set parameters (temperatures, preheating and cooking times, cooking pressure) Then, pushing a single key will automatically start the procedure : platen rising, contact during pre-heating time, degassing, pressure and cooking , opening when programmed time is over.

  • Pressure by motorized hydraulic pump, with separate jack to avoid heat transmission to hydraulic parts.
  • automatic control of manufacturing cycles
  • preheating and curing time are controlled by a digital timer
  • switch for additional degassing
  • emergency stop
  • manometer for pressure control
  • 2 PID electronic controllers securing perfect accuracy and distribution of temperature for pre-inked and rubber stamp making

Faq

A (rubber) stamp is meant for marking on various supports.

It is mainly used to print information on administrative documents (validate a document with company stamp, obliterate  a mail,  date a document..) or artistic creations (greeting card or announcement decorations, labels..)

It is made of :

   => An inked pad

   => A rubber or polymer layer containing pattern

   => A mount / handle

Ink can be adapted according to application : there are  acid inks for engraving, inks for textile, for metals, for outdoor uses…
