Blackening Chemicals

A simple and cost effective process for chemically blackening iron and steel at room temperature is now available requiring no chemical knowledge and producing no environmental hazard. Blackfast chemicals process is suitable for engineering works, workshops and tool rooms. By straightforward immersion in a series of tanks precision-engineered components are rendered a deep black with no change to their overall dimensions. The benefits are lower cost, fast turn around in finished product, reduction in component stocks, flexibility and in-house quality control.

The simple nature of the room temperature process means that a blackfast line is equally suitable for a production employing a fully or semi automatic line or for a manual line in a workshop or a tool room. Unlike conventional methods of blacking whereby components are immersed for 30 minutes in cauldrons containing chemicals boiling at 140 deg c , the room temperature process is essentially non hazardous and is quick and easy to use. The blacking solution does not carry a toxic or corrosive label.

Those companies that operate their own hot blacking line or are considering changing their finishing process can benefit in the following ways by adopting a room temperature blacking line. There is no expensive capital equipment required-plastic or rubber lined tanks will do. Extraction equipment is either minimal or not necessary as there is no damage to the fabric of the facility- a common fault given the corrosive nature of the fumes from the hot blacking line. There are no heating costs, the solution can be used immediately and does not require two hours to reach operating temperature. There are no salts that subsequently leach out into holes and small orifices. A short dwell time allows rapid through put of production and higher coverage per gallon. The health benefit to the operator is immeasurable.

The owner of an efficiently run blackfast line will benefit from a number of cost savings. Firstly, completed production no longer has to leave the faculty for metal finishing out-house, which will avoid production delays and reduce stock holdings. Quality control is maintained in house. A cold blacking line gives the operator a high degree of flexibility and when not in use the solution can be left without deterioration. Start up is instant.

The blackfast solution control is simple and replenishment is by topping up. Dumping is not necessary as with other systems. The blackfast process is convenient and can be located anywhere without the need for ventilation or a complicated control procedure. The solutions are stable, reliable and surprisingly easy to maintain.

A uniform black finish of steel components is, today, extremely popular and adds considerably to the perceived value of the product. This, combined with the unique quality that the component dimensions are not altered and an even colour is achieved over blind holes and threads makes it a must for any precision engineer. Any precision engineer company manufacturing metal parts, which require coloring and corrosion protection without resulting in dimensional change, would benefit by installing their own blackfast room temperature blacking line.

Machine builders : Machines for printing, drinking cans, cigarettes, textiles, shoes, food processing, packaging, pipe bending, gas turbines, slide systems, conveyors.

Workholding : workholding equipment specialists and tool rooms.

Automotive : specialist equipment companies, tools and racing / sports sector.

General industrial equipment : clutches, transmissions, drives, hydraulic blocks, and fasteners.

Metal working contractors : the largest single market group.

Gun and model hobbyists : Blackfast is sold as small blacking kits directly to the public. This is usually undertaken by a distributor who specialises in this industry sector.

Metal finishing contractors : Mechanical industry applications.

User Benefits:

1) No dimensional change:
Many machined parts are manufactured to a tight tolerance, which means plating or painting are not acceptable.

2) Corrosion resistance:
The black surface absorbs wax, oil or rust preventative sealants to give corrosion protection.

3) Sales appeal:
A durable black finish enhances the appearance and value of a wide range of manufactured articles.

4) Safety By reducing light glare from moving tooling or machinery, it eases fatigue and contributes to operator safety.
