How Our Controlled Drugs Cabinets are manufactured.

Controlled drugs cabinet bodies are made from blank sheets of steel.

Laser cutting controlled drugs cabinets

The controlled drugs cabinets we manufacture begin as flat sheets of 2mm thick cold reduced steel. British Standard 2881:1989 level one and the misuse of drugs (safe custody) regulation require a minimum thickness of 1.5mm steel. We prefer however, to make ours from thicker material. This makes them much stronger cabinets than our competitors.

Our Laser cutter enables us to accurately and consistently reproduce the blank component shape. Each component part of our Medicine and Controlled drugs cabinets have the developed shape designed so when they are formed each part fits correctly. The accurately and fit of each formed part reduces the joint gaps between the components. A small joint gap helps the welding operator achieve a neat weld and with lower heat input into the joint creates less weld distortion. The smaller weld bead allowed by the tighter joint gaps also reduces the amount of weld requiring removal. The surplus weld bead is smoothed off using a sander which smooths the weld bead making it invisible once the cabinets have been powder coated. To further reduce the cleaning off time involved in the cabinet manufacture we use a method of welding called Tungsten inert gas or TIG welding. Although this is a slower process than the alternative Metallic inert gas or MIG method it creates less weld bead and no weld spatter. This further helps the cleaning off process involved in the manufacture of the cabinets.

Our in-house Laser cutting machine is again used in the making of both the Medicine cabinet and controlled drugs cabinet doors. These blanks are laser cut to the correct size and shape ensuring a good and

consistent door profile. Lock hole profiles and any other holes and bend notch clearances are included at this laser cutting stage of manufacture. The door profiles are formed to the required shape using a machine called a press brake. We use much the same process on the cabinet bodies too.

How we form the drugs cabinet to shape.

The steel blanks are then formed to the required shape using a "Press brake". This machine exerts 130 tonne of pressure on the steel through a top and bottom "V" shaped tool. This process forms a tight bend in the steel. This bend is to a predetermined angle to achieve the required bend in the metal. The formed cabinet bodies and doors are then passed on to other operators. This is where the lock plates and door shelves are welded together. The two Press brake machines we use to bend the cabinets are fully computer controlled. This level of control ensures that each cabinet in our range will be formed to the correct and required size. This is enabled by pre-programming the sizes and bend angle of each cabinet in our extensive range into the machine. The operator then selects the correct program to go with the cabinet blanks to be formed. The machine will then select the right tonnage required and adjust the back stop and bend angle to suit each of the many bends required to for a cabinet.

Welding together the formed parts to make a Controlled Drugs cabinet.

Welding drugs cabinets together

Operators assemble the body and sides of the cabinet in the following way. During the laser cutting of the blanks registration points are included which act as reference points allowing the

operator to line up each part accurately and correctly every time. Then small tack welds are applied at various intervals along the joints to position the component parts correctly prior to welding. The controlled drugs cabinet doors are then offered up to the cabinet. This ensures the correct gap between the door and the cabinet. The Misuse of Drugs (Safe Custody) Regulations 1975 requires a maximum gap of 3mm between the door and the jam.

A further requirement of the Misuse of Drugs act is that anchor plates are placed over the holes through which the cabinet is fixed to the wall or floor. The anchor plates must be a minimum size and thickness to comply with the act. The purpose of these anchor plates is to reinforce the area around the fixing holes. Helping prevent forced removal of the cabinet from the wall or floor to which it is fixed. The anchor plates should be a minimum of 3mm thick and have a minimum surface area of 19000 square millimetres. Also, the controlled drugs cabinet should be fixed to a wall or floor using the fixings provided by the manufacturer. This so it can resist a load of 980 Newtons of force before it is moved from the mountings.

Finally, when the operator is completely satisfied with the fit of all the cabinet parts and all the relative items have been installed correctly the cabinet is fully welded. This is another requirement of the Misuse of Drugs (Safe Custody) Regulations, that the cabinet features a fully welded construction.

Powder coating the finished cabinet component parts.

Powder Coating Controlled drugs cabients

The finished Controlled drugs cabinet assemblies are taken to our purpose-built powder coating plant which is adjacent to our fabrication facility. Here they are thoroughly degreased and cleaned to remove all traces of grease and dirt.

The parts are then suspended from an overhead conveyor. This conveyor will transport the manufactured cabinets around the whole powder coating process.

The powder coating process consists of a powder which is applied using a special electro static gun. The gun applies up to 100,000 volts of positive static charge to the fine powder particles. These particles are aimed at and attracted to the negatively charged work pieces. These parts are electrically earthed so the charged particles stay on the metal. They stay there until permanently melted and fused into a solid coat in the curing oven. The electro static charge in the powder causes the particles to go into the corners and behind flanges ensuring full coverage of all the metal parts.

The curing oven is a long tunnel through which the cabinet body assemblies are passed after the powder has been applied. This oven is at a constant 215 degrees centigrade. The cabinet parts need to be at that temperature for 12 - 15 minutes. This allows the powder to form into a solid coating.

Upon exiting the oven on the conveyor, the parts cool and are removed. They are then taken over to the assembly bench.

Final assembly.

Now the Controlled drugs cabinets are almost complete.

The parts are checked and assembled to ensure they are compliant. They are compliant with both BS2881:1989 level one and Misuse of Drugs (Safe Custody) Regulations 1975.

The doors are riveted to the cabinet body using a compressed air riveting gun.

Copntrolled Drugs Cabinet Stock

The doors are riveted in place after powder coating. This is because both parts of the drugs cabinet need to be powder coated separately. This ensures a good cover of powder in all areas.

The Euro style locks are fitted to the doors and pre-packed shelves placed inside the cabinet.

Packaging and warehousing.

The finished Controlled drugs cabinets are wrapped in protective foam and boxed ready for shipping.

We keep stocks of all our products so can usually dispatch Drugs cabinets from our warehouse the next working day.
