What is Scientific Injection Molding?

There has been an upsurge in the demand of dimensionally stable as well as accurate parts and components in the medical sector. Several medical component manufacturers have examined the developments in injection molding and are keen to incorporate the technique for quick production of dimensionally precise medical equipment. Whether it is tight tolerance or thin wall, each of the demanding characteristics of medical components can be catered by a type of injection molding known as Scientific Injection Molding (SIM).

The SIM is an attempt to make the most of the current injection molding procedure. The Scientific injection molding can work with the conventional materials such as thermoplastic materials and other unconventional substance such as silicone rubber, thermoset plastics, high consistency rubber, and the like.

Why scientific injection molding is not a fixed process?

The process of SIM is variable. It depends upon the nature of the manufactured medical device. A little tribal knowledge and past practices help in further tweaking the existing molding procedure. The fine-tuning of the existing injection molding continues until the desired specification of a product has been met. However, building a robust SIM is a time-consuming procedure and requires process engineers to take into consideration several factors such as:-

• PET preform mold design/construction
• Part design
• Process parameters (mold temperature, injection speed, melting temperature, hold pressure, cooling time, etc.) 
• The molding machinery at work
• The nature (including viscosity) of the material to be used

How SIM and lean manufacturing are related?

For many industrial players – especially the ones believing in lean manufacturing – scientific injection molding has become a culture. Lean manufacturing and SIM are interrelated as both emphasize on eliminating waste (such as downtime, over processing, defective products, excess inventory, to mention a few) and, thus, reducing the overall cost.

SIM is a data-driven approach based on thorough scientific analysis of the prevailing molding process. Several PET preform manufacturers are developing high-quality single stage Mould that is apt to be used in a scientific injection molding.

Preform Molding: The Key To Cut Cost And Increase Flexibility

PET systems having low cavity pet preform mold take minimal mold changeover time and cut the overall conversion costs. Indirectly though, we witness the wonders of Preform Molding technology on a regular basis.  The Preform Molding is used for shaping our everyday products ranging from cell phones to toys. Without Preform Molding, getting exactness in shapes of products was a wistful dream. The more complex geometries of products can be physically conceived by Preform Molding. For instance, the shape of a bottle is neither fish nor fowl – it is a cross between cylindrical and conical; such a shape is given to the bottle by using the marvels of Preform Molding.

Advantages Of Preform Molding:

•  Cast away the manufacturing woes associated with a product having complex contours with the help of Preform Molding
•   This molding technique not only helps in giving the product a desired shape, but also aids in making it looking visually appealing 
• Some fresh developments are under process to make the Preform Molding an eco-friendly technology – the start is done by making such Preform Molds that are reusable and recyclable  

  The pet preform mold, which are made using Preform Molding, cools down and gets heated in no time
