Injection Molding/ Manufacturing

Injection molding is a manufacturing process where heated molten plastic is forced into a mold cavity under pressure. A mold cavity is a negative of the part being produced, when the cavity is filled with plastic, it is cooled and the plastic becomes solid material resulting in a completed positive component.


Screen Printing is a wet process where ink is squeezed through a fine mesh material onto the part to be decorated. A film positive is made of the artwork and then laid over a fine mesh material which has been tightly stretched and fastened to a frame. The mesh material has been coated with a light sensitive emulsion and the film and screen are then exposed to a mercury vapor light. This exposure hardens the emulsion on the screen creating a solid barrier. The portion of the screen that was covered by the film positive remains soft and is washed off the screen with a pressurized water spray. The completed screen now allows ink to pass through this washed out area while preventing ink from passing through the hardened emulsion. This washed out portion of the screen is now an exact duplicate of the artwork to be placed on the part. The screen is then mounted in the screen printing machine and clamped in place. A fixture is mounted under the screen which is designed to hold the part to be printed in the correct location. The part is then placed in the fixture and ink is added to the screen. The ink is squeezed through the screen with a rubber squeegee while the part is moved under the screen, allowing the ink to be placed on the part.
One of the main benefits of screen printing is the unique visual result it creates. The inks are very durable, the colours are extremely vivid, particularly for outdoor use. As such for large production runs it continues to be one of the most effective and economical decoration methods available.

Pressure Sensitive/Self-Adhesive Label is a label construction made up of three layers; a face material, a pressure sensitive adhesive, and a backing sheet coated in a release agent. The layers are laminated together and then die cut to produce the individual labels. The final product can be in sheet, roll, or fan-fold format. Pressure sensitive labels use an adhesive that is tacky in normal conditions, meaning the labels only need the pressure of a finger or hand to be applied. There are numerous advantages of using a self-adhesive/pressure sensitive label over conventional decoration. These include efficiency, cost effectiveness and most importantly quality. Pressure sensitive labels offer high-quality graphics and above average durability. These labels offer flexibility in your design, as they can be customized with a variety of add-ons. Other reasons for choosing pressure sensitive labels include:
• Highly quality graphics
• Variety of materials to choose from
• Custom die-cut options for any shape
• Multiple finishing options (embossing, cold & hot stamping, tactile varnish, etc)
• Fits any container with a smooth surface

Heat Transfer Label is a dry printing process like hot stamping where a pre-printed graphic image is trapped between a heated plate and the part. Heat and pressure is applied to the part and the graphic is then permanently bonded to the part. The advantage of the Heat Transfer process is that multi-colour graphics can be applied to a part in one pass; therefore, the customer can have the benefit of a multi-coloured print while only having to pay the cost of a single application.
