The pharmaceutical industry brings out products in various forms. The product ranges include tablets, capsules, liquid medications, powders, injections and many more. These different kinds of products are packaged using different kinds of filling machines.
Form, fill and seal machines are filling machines that use flexible, heat sealable, plastic film for making packages which are filled with a product and sealed. Different kinds of filling machines are used for containers like bags, bottles and cans. Filling machines used for such containers can be adjusted to fill a predetermined quantity of product into each container.
Certain filling operations require the use of leveling resins and filling compounds to level surfaces and fill cavities. Powder, granular and other bulk solid materials form the bulk of veterinary pharmaceuticals. Solids feeders are used to deliver such products along a process line on to storage bins, conveyors and product containers.
Several pharmaceutical products are powders that are compressed and compacted into various shapes for ease of handling. Powder compacting equipment is used to shape powders into predetermined shapes.
Some pharmaceutical products can be formed, filled, sealed, wrapped and packaged using sophisticated automatic machinery. The type of product and the cost factor determine the use of such products.
A few different types of closing styles are used in the pharmaceutical industry. Closing machines are pressed into use for tying wires, narrow metal straps or tapes around the neck of a bag; placing lids on cans and drums and other kinds of closing operations.
The pharmaceutical industry has special filling needs like filling vials and infusion bottles. There are filling machines that handle this kind of a filling at high speeds. Most machines of this kind can fill 400- 500 bottles a minute. This is necessary as several liquid medicines come in individual dose packing. Medicines for injections fall in this category. So there is a high volume in terms of numbers of individual dose bottles that are required on a regular basis.
