Designing the perfect part is something that all designers strive for, but also something that is usually exclusive to sketchbooks and 3D software modeling. When it comes to actually producing a part, designers are forced to face the limitations of production and budget, and often have to make design compromises due to costs, part volume and geometry considerations, and other factors.

With that said, advances in materials technology have given designers newfound freedom. In particular, the advent of high density thermoplastics have given designers much more freedom in regards to part geometry and volume by enabling them to place precise amounts of weight at particular locations. Such high density thermoplastic materials can be injection molded into complex geometries at densities up to 11 g/cc, allowing them to replace metals and other standard materials, and eliminating the need for costly secondary machining operations. Part makers can now mold plastic parts at very high densities, as opposed to having to buy blocks of metal and machine them to shape. To achieve this, high density thermoplastic compounds are required, which can deliver outstanding performance and minimize cost in numerous weighting, balancing, vibration dampening and radiation shielding applications.

These high density materials can also be easily modified to meet a wide range of physical property requirements, such as tensile strength, flex strength, flexmodulus, and heat resistance. Moreover, these high density injection moldable compounds assist by freeing up space in components parts, thus providing designers more design latitude and freedom for designing. Apart from these benefits, these compounds are completely lead free and nontoxic, meeting theincreased demand for high density, lead free products.

These high gravity compounds can be used in a variety of applications. Firstly, they are ideal for weighting and balancing applications. They have been utilized successfully to produce hub odometers, frangible projectiles, instrument housings, return weights, inertia discs, golf club weights, manual transmission shifter cartridges, and more.

In automotive manual transmission shifters, high density material molded in the form of shifter cartridges increases the weight and thus improves the feel at a customer touchpoint, as well as decreases the vibration transmitted through shifter. The reduced vibration improves the customer experience and increases the life of the equipment by reducing wear. As they do not contain toxic materials, these high densitymaterials are highly eco-friendly, and are used to replace lead in a number of applications. One of the most significant uses of these high density materials are in the production of lead free, frangible ammunition. These high density materials aremolded with either copper-filled or tungsten-filled compounds in the form of small caliber rifle and handgun projectiles, which have improved safety by eliminating any lead contamination risksorricochet potential at firing ranges. Unlike lead bullets, frangible ammunition made with high density materials are have no ricochet risk as they powderize upon impact with the target.

It is evident that high density materials have helped revolutionize part design by providing more part volume and part geometry freedom to designers.
