Rubber Cleaning & Conditioning Sheet

GENERAL

  • AMECLEAN AC (Cleaning Rubber) can effectively eliminate the pollutants and stains formed on the mold surface, through physical and chemical mechanism.
  • AMEWAX AW (Conditioning Wax) protects mold surface and provides releasing after cleaning.

FEATURES

A) Performance & Effect
  • Less smell and smoke occurring during and after cleaning.
  • Good flow characteristics enables to clean and mold corner and thin gate area.
  • No incomplete fill problem for complex shapes and micro size of mold cavities.
  • No mold abrasion and corrosion (no sulfur).
  • Unlike melamine cleaner, can clean the air ventilation area.
B) Economical Efficiency & Productivity Improvement
  • No dummy lead frame and preheating.
  • One size covers many packages. Less inventory management.
  • Shorter cleaning cycle thanks to enhanced cleaning effect.
  • Less down time and easy to use.

Chemical Cleaning

Mix cleaner and surfactants into rubber.

  • Polar cleaners used.
  • Ethching of contaminants surface, plasticizing.
  • Adhesion promoter used to pull out contaminants.
VS

Mechanical Cleaning

Abrasion by Filler with close contact to the mold surface and adsorption.

  • Tackifier used.
  • Flowability, thickness, pressure optimization.

What differential of AME CLEAN with AME WAX

AME CLEAN FEATURES
  • Good workability.
  • Enhanced cleaning performance.
  • Controlled flow ability depending on package type.
  • Less fume & odor.
  • No rusting chemicals.
AME WAX FEATURES
  • Good releasing performance ensures trouble free production for sticky green, clear, white EMC.
  • High temperature resistance grade (non yellowing) available.
  • Less wax build up.
  • Good work ability, less fume & odor.
Cleaning Procedure
  1. Place AMECLEAN on mold.
  2. Mold for 180~300 sec and remove cured rubber. Blow rubber with air gun for better releasing and reduce fume & smell.
  3. Repeat the process (3~8 shots) until mold cleaning is complete.
  4. Perform 1~3 shots of AMEWAX.
  5. Run dummy buyoff and check the appearance.
Packing and Shelf Life
  • Net weight 10kgs per carton box and the rubber sheets are sealed in a PE zipper bag.
  • Store the rubber sheets at 25°C or below and the shelf life is 12 months from manufacturing date.
Cautions
  • It is recommended to store in well ventilated place.
  • Care should be taken for skin not to direct contact with hot cured rubber sheet.
  • Avoid storage at temperature above 30°C.
