Plastic Industry

Though you might not realize it, dry compressed air affects each and every unit in Plastic industry.

Applications

Forming
Mold Press Powering
Tool powering
Injection molding
Blowing work piece from production molds
Clamping
Conveying plastic pellets
Cleaning

In plastic industry manufacturing units, generally following compressed air powered pneumatic Systems are used :

Pneumatic Control and Actuators
Forming Machine
Cutting equipment
Increase in downtime
Adhesive Station
Conveying Machine

Problems
A major problem in compressed air systems is the presence of water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality.

If the contaminated compressed air will be used through pneumatic tools and machines then there will be following problems :

Malfunctioning of pneumatic tools and machines
Sluggish and inconsistent operation of valves and cylinder
Corrosion in pipe lines, cylinder and other components
Increase in downtime
Increase in maintenance cost of pneumatic machines / tools / controls.
Freezing in exposed lines during cold weather.

Moisture in compressed air also leads to problems like :

Loss of clarity i.e clouding of plastic bottles / containers
Loss of strength of plastic bottles / containers
Contamination of plastic resin
Internal bubbles / pockmarks in the bottles / containers

The Delair Solution

Remove water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants from compressed air.

Delair offers wide range of refrigeration dryer and adsorption dryers which removed water / moisture from compressed air.

Delair refrigeration dryers

This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.

Delair Adsorption dryer

The dryers is based on the principle of heatless regeneration and the physical properties of ther desiccant to adsorb and desorb the water vapour, It uses pressure swing principle / purge air to regenerate the desiccant bed.
