FAQ


F A Q – Masking

1. I paint 2 colours after each other and I´m getting colour/surface changes under the tape!?

  • Do not use TGIC-free paint!
  • Cure properly (use oven logger)!
  • Test TO, TB!

2. The green tape doesn´t stick?

  • Surface structure (casting etc.)?
  • Dirty surface?
  • Efficient sticking area?
  • Old tape?
  • Test TR or TB (thicker adhesive)!
  • Try to press on the tape!

3. How big discs can you supply?

  • 1x1 or bigger (but it´s not a handable format)
  • With print approx. 320x480
  • If nothing else is agreed - delivery on rolls

4. Can back side (liner) of a disc-set be slited?

  • Yes

5. What is acceptable storing-time for tape?

  • Approx. 6 months

6. I need special size of special discs with special printing!?

  • No problem. Tooling is cheap
  • We can also offer ERD for this purpose
  • No min. quantities, but about 10.000 pcs to get a good price

7. Doesn´t paper/MDF/cork burn at 200 Celsius?

  • No, but it is close to the limit

8. Does silicone shrink at higher temperatures?

  • Yes, but less than 1%

9. How many times can a silicone plug be used?

  • Depends on the treatment (scratching)
  • Theoretically silicone rubber could be used a several hundred times at 200ºC
  • Flakes are causing the biggest problems and limit normally the use

10. How many times can I use an EPDM plug in powder coating?

  • A few times, then the material gets hard and brittle

11. How do I get rid of flakes?

  • It´s difficult
  • Washing + mechanical schratching/blewing

12. Can silicone rubber absorb liquids?

  • Yes, petrolbased chemicals are hard for silicone rubber (TriChlorEthylen, Toulen etc)

13. Can silicone rubber cause silicone contamination?

  • Normally not, but physical mistreatment of the rubber can cause (limited) problems
  • Silicone oil rests are exhausted in postcuring process (always done)

14. Is it possible to glue silicone rubber to steel?

  • Yes

15. DSM 10 (magnet sheet) falls off in the oven!?

  • The temporary loss of magnet power is enough to make it fall off.
  • Strong air flows
  • Too small masking format
  • Too small contact area

16. I want a rubber cloth that is 20mm thick!?

  • Sandwich construction (8+12 mm)

17. Is it possible to watercut with several beams parallell?

  • Yes, 4 beams if details are not too big (4 abrasive)
  • The material can be "stacked", but then cutting quality is diminishing

18. In which sizes can Colour match panels (PP) be produced?

  • Tooling is available for 30/40/50/60x100 mm (hole concentric on shortest side) and 100x30-infinity mm (hole concentric on 100 mm side)
  • By watercutting almost every size can be done. Cutting quality will be a little bit rough, but logotype might be cut

19. We have been using the same conical plug for several years and with the last shipment we got plugs that broke!?

  • Generally there are variations in hardness and tear strength that depends on both material and production
  • Are the way of using the plug "on the border" of what the material can perform there will be problems at some point
  • Has the way of using it changed (new staff or new paint for example)?
  • What does the hole look like? Sharp edges (threads)?
  • Are tools (cutting pliers) used to remove the plugs?
  • Has any alternatives been tested (GTM etc)?

20. We´ve been testing GGM06, but the problem is that it´s hollow, which means that flakes are left inside after cleaning it?

  • Is it economical to clean it?
  • The price is 0,40 SEK/pcs and every working second cost approx. 0,07 SEK. What is the real cost for washing a plug like this?

21. I think that paint sticks less on pink plugs than on yellow ones!

  • There shouldn´t be any differences
  • Colour is added at small doses and doesn´t affect physical properties. Colour is there just to make the handling easier

22. Can you cut tubes with 45 degree angle?

  • Yes

 

F A Q - Hanging


1. How much copper is there on a hook?

  • Less than 1g/m wire (0,5-1 my thin layer)

2. Why is there copper on the wire?

  • To get a clean wire. Copper is a last step lubricant by wire-drawing.
  • Better earthing? No, not really, but some other advantages like less oxidation and better welding possibilites

3. Why a DV hook instead of a radius hook?

  • It can be used more times with maintained earthing (contact)
  • DV is a safer hook (higher load margin)
  • Comparison of 100x2,0 hook DV vs R:
    - Same load capability before any stretching (approx 5,5kg)                                                            
    - Different maximum load before dropping product (26 and 10,5kg)

4. I have a product weighing 4 kg. Which wire dimension shall I use?

  • Hook type?
  • Security level?
  • Dynamic loads?
  • Cleaning/burning of hook?
  • See recommendation table in the handbook!

5. I get too big hanging marks with a 3mm hook. What shall I do?

  • Arrow, BHL or BH
  • Spring wire/thinner diameter
  • Hang at a covered/hidden spot
  • Square wire
  • If a product is hanging in two hooks - use a secondary load bar to avoid twist marks!

6. Your hooks can´t stand so many burn-offs as your competitors spring wire hooks!

  • Is our price better?
  • Our hooks are not meant to be burned-off
  • True comparison
    - Hanging-mark size
    - Cleanliness
    - Handling, burning and washing (sorting)
    - Powder consumption
    - Capital cost
    - How many extra seconds can I handle the spring hook before it gets more expensive?

7. We have capacity problems, but we don´t want to invest money in expensive special jigs!?

  • HQS
  • HQL
  • Use system 1000/1100/2000 in 2 or more "lines" (use depth) or use coupling plates.
  • BHL systems & frames

8. We are getting our rail and conveyer full painted!?

  • Earthing!!
  • Deeper slot
  • Check air flows in powder cabin

9. For how long can we use a hook?

  • Depending on where hanging point is situated and the hook design
  • Until resistance exceeds 1 Mohm (US safety recommendation)
  • Use CGT II

10. Why H11B instead of H1B?

  • Heavier (up to 5mm hooks)
  • Can be cleaned with burn-off procedure

11. I have problems with dust falling down from my conveyer

  • Clean the conveyer often and use the right oil
  • Get a waste collector!
