subject: Better Results With High Performance Additives: Injection Molders [print this page]

Injection molding is one the most common manufacturing techniques for

making products having complex shapes and structures. However, the

process requires preheating of polymers like ABS, HIPS, Nylon, filled

PP etc. for up to 4 hrs and consumes expensive electrical energy.

Also, the manufacturers often have to deal with problems like breakage

or poor surface finish, whenever using recycled polymer or fillers.

If the preheating is not done, the moisture present in the polymer can

create various surface defects such as blisters and delamination,

which are not only aesthetically undesirable but also can also

severely reduce the quality of end product.

Besides this, there are problems of poor dispersion of color

masterbatches or poor flow rates which harass the manufacturers. These

problems come from the variation of Melt Flow Indices (MFI) from

virgin polymer to recycled one. Most injection molders agree that

using additives gives better products and generally enhances

productivity.

Keeping the myriad problems faced by injection molder, Vin Industries

has created EliHeat and MoldWel. Both are high performance additives

for injection molding.

When mixed with the polymers, EliHeat reacts with moisture and forms

stable compounds which do not evaporate and create surface defects.

This also means that the additive gives its full weight to the end

product.

EliHeat is a very useful additive for injection molders. It removes

preheating, which not only shortens the process time but also cuts the

power consumption and other costs drastically, said Rohit Mahajan,

product specialist at Vin Industries.

On the other hand, MoldWel lowers the viscosity of the mixture and

equalizes the MFI of various ingredients, resulting in better flow and

productivity, besides ensuring proper dispersion of color in the end

product.

High quality surface finish, optimum color dispersion and better

physical properties in end products are some of the major advantages

of the additive, which comes in opaque, light gray granules.

According to the company, both the additives have generated a loyal

customer base due to their high performance and value addition.

Based in New Delhi with a strong sales network throughout India, Vin

Industries is the country's leading manufacturer of niche additives

for the plastic industries ever since the company's inception in 1997.
