A low pressure structural foam injection molding also called as low pressure molding process utilizes nitrogen combined with the melted polymer so that the weight and density be reduced of the finished product. Once the solution gets ready then it is injected into the mold and then the gas expands so that the mold cavity can be filled with foam. This low pressure molding process will lead to the reduction of the weight of the finished product by 20% in comparison to other injection processes used. Now, as the whole procedure is done at the lower pressure, so, therefore, the plastic parts produced are larger and more structurally stronger if they would have been made using high pressure method. Now, this was all about low pressure structural foam injection molding method, moving on further, let’s discuss something more about this method.
When to Opt for Low Pressure Structural Foam Injection Molding
Do you desire of thickness of the wall in your parts? Do you need structural integrity, stiffness and low weight, high resistance? If so, then you should adhere to low pressure molding as this is the exact solution which can make your production rate and production quality both not to get compromised at any level in the manufacturing procedure. As the method provides such advantageous qualities which when applied to the parts work wonders when multiple parts are molded together and eventually results in offering low costs and refine the quality.
With such merits added to low pressure structural foam injection molding process, it is now very much clear in interpreting that the use of metal castings, fiberglass and rotational molding can be easily replaced for the manufacturing of plastic components and also the products with reduced cost, high quality and accuracy can be produced and giving an enhanced productivity.
