Questions And Answers

Q1:Can you just dip it quickly?
A1:Electroplating is a plating process in which metal ions in a solution are moved by an electric field to coat an electrode. The process uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal (i.e., zinc, cadmium, etc.).
Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g., abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.) to a surface that otherwise lacks that property.
Another application uses electroplating to build up thickness on undersized parts.
Electroplating and its process takes roughly 3 hours or more from the time of arrival to the final quality inspection, there are no shortcuts or "just dipping" of products.
The condition of the part you're having plated (parts in good repair require less pre-processing), and our current workload, needs to be factored into this time and therefore might take longer. Pre-Clean, Clean, Acid pickel, PLATING, Post-treatments, Drying.
This question is normally followed with question 2.

Q2:Can I have it yesterday?
A2:Read Question1

Q3:How long will it take to complete a job?
A3:Turnaround time depends on the job (for example, quantity of pieces) but we have built a reputation on being one of the quickest electroplating shops in the industry.We work a 2 shift system, sometimes we are producing 24hrs a day. We strive to satisfy our customers needs and therefore plan our production so that the goods brought in can be collected the following day. In busy times, and if the the steel item needs more preparation, then a 2 to 3 day waiting period may be required on our main lines.
These times can change, AND it is possible for a same day delivery.Please contact us so we can best estimate how quickly we can turn your plating project around.

Q4:What is the largest size you can electroplate?
A4:Team Plating Works cc specialise in barrel plating of smaller components. We do not do any jigging (hanging) of items.

Q5:On what types of metal can you plate?
A5:We can plate over most types of metal including steel, brass, bronze, copper, zinc die cast

Q6:What are your working hours?
A6:Although we are producing 24hrs a day,and to ensure your goods get to the correct plating department, our intake and dispatch hours are from 08h00 to 12h00 Monday to Friday and 13h00 to 16h00 Monday to Thursday and we close off at 15h00 in a Friday.

Q7:What are the salt spray hours of Zinc Passivation Layers?
A7:There is a WEAK correlation between the duration in salt spray test and the expected life of a coating since corrosion is a very complicated process and can be influenced by many external factors. Nevertheless, salt spray test is widely used in the industrial sector for the evaluation of the correct application of coatings on finished surfaces or parts. Therefor it is a myth that the higher the corrosion resistance, the longer the item will last in real life applications. This is especially true when dealing with organic coatings.

Q8:How long does Zinc and Passivation Layers last in the environment?

Q9:Is Cadmium illegal or has it been banned?
A9:Cadmium is part of "The Restriction of Hazardous Substances Directive 2002/95/EC" Read Rohs below for further details.

Q10:What is Rohs?
A10:Rohs is the acronym used for "The Restriction of Hazardous Substances Directive 2002/95/EC " which restricts the use of certain hazardous substances.
Rohs basically restricts the use of six hazardous substances. Please note the wording "Restrict" does not mean a substance is banned. Some restricted substances cannot be substituted in certain applications and therefore can not be banned, but rather restricted.

Q15:All about embrittlement?
A15:Hydrogen embrittlement can occur during various manufacturing operations or operational use - anywhere that the metal comes into contact with atomic or molecular hydrogen.
Hydrogen is introduced to the surface of a metal and individual hydrogen atoms diffuse through the metal. Because the solubility of hydrogen increases at higher temperatures, raising the temperature can increase the diffusion of hydrogen. When assisted by a concentration gradient where there is significantly more hydrogen outside the metal than inside, hydrogen diffusion can occur even at lower temperatures.
These individual hydrogen atoms within the metal gradually recombine to form hydrogen molecules, creating pressure from within the metal. This pressure can increase to levels where the metal has reached a point where it cracks open(hydrogen-induced cracking)
Processes that can lead to this include: cathodic protection, phosphating, pickling, and electroplating.
For example:
Arc welding, in which the hydrogen is released from moisture from the coating of welding electrodes, a special low-hydrogen electrodes is used for welding high-strength steels.
Other mechanisms of introduction of hydrogen into metal are galvanic corrosion, as well as chemical reactions with acids or other chemicals.
Hydrogen embrittlement can be prevented through several methods, all of which are centered on minimizing contact between the metal and hydrogen, particularly during fabrication. Embrittling procedures such as acid pickling should be avoided.

If the metal has not yet started to crack, embrittlement can reversed by removing the hydrogen source and causing the hydrogen within the metal to diffuse out through heat treatment.This de-embrittlement process, known as "baking", has to be completed generally between 1-4 hours after the hydrogen has been introduced, otherwise the "damage" will be permanent. Even though all procedures are followed, this "baking"is not always entirely effective.

In the case of welding, often pre- and post-heating the metal is applied to allow the hydrogen to diffuse out before it can cause any damage. This is specifically done with high-strength steels and low alloy steels.Due to the time needed to re-combine hydrogen atoms into the hydrogen molecules, hydrogen cracking due to welding can occur over 24 hours after the welding operation is completed.
