Dear sir,
Good Day.
I am Prem Kumar Sharma from Kolkata. I am representing a South Korean company for buying Insulators. I have myself lived in Korea for 25 years and did business in South Korea and still I have business with Koreans. 

I have below given enquiry for :
 1) Standard supporting insulator
 2) Supporting insulator for expansion joint
 3) Supporting insulator for anchoring device
 4) Supporting insulator for end approach

1. Sample production for 4 types of insulators
    1) Sample production schedule
        - Drawing and mold making
        - Sample production schedule (schedule by process)
        - Insulator property test schedule for 4 types (refer to parts specifications and test items)
        - The production quantity for testing is produced independently
     2) Sample production quantity
       - Standard type - 20 pieces, Expansion - 10 pieces, Anchor type - 10 pieces, End approach - 10 pieces (total: 50 pieces)
       - This is a sample for domestic self-certified testing.
     3) Test on sample production
       - Submission of test report
       - The quality performance must be equal to or better than the report attached before.
       - Videos and photos during the test are required.

2. Production schedule for mass production
     1) Mass production quantity
      - Standard insulator : 28,000EA (1st and 2nd delivery)
      - Insulator for anchoring device: 980EA  (1st and 2nd delivery)
      - Insulator for expansion joint: 1,680EA  (1st and 2nd delivery)
      - End-approach insulator : 1,250EA  (1st and 2nd delivery)
     2) Test and delivery availability schedule
      - 1st and 2nd partial shipment
      - Test period for 4 types of insulators

3. Estimated price for delivery and mass production
    1) Sample production
      - Mold production and test cost, etc.
      - Sample production delivery amount (50EA)
    2) Mass production 
      - Each 4 types of insulators

If you are manufacturing the said insulators then please contact me for further informations.

Thanks and best regards
