Plastic Injection

Our business:
Plastic Injection

Nord West is a market reference when it comes to Plastic Injection of technical parts as it works with the best technology, for this to happen, in addition to having a highly qualified technical team that systematically participates in training and recycling programs, has a manufacturing park formed by high performance equipment.

The Nord West differential
Material
With the increase of usage of plastic materials in most diverse markets and technologies, more and more companies are looking for complete solutions for their product, focusing on their biggest goal, which is to define the design of the desired product, aligned of course to the correct choice of the raw material to be considered.

Product
From a careful analysis of the product, our objective at this point is to present a series of suggestions in order to minimize as much as possible complications that may impact the final appearance of the product, such as:
  • Surface marks resulting from thicknesses
  • Shapes not suitable for the plastic material to be used
  • Definition of the ideal raw material
  • Definition as to the strategic of the mold.

Mold
The option for not having your own tooling worshop comes from a strategic decision to focus on the core business, which is the injection process, however we understand that this is a determining point for the success of the whole process, for this reason, in the development of new projects we apply all our expertise evaluating critical points that will directly impact the injection process, such as:
  • Cooling system
  • Conception of the mold in general (extraction system, applied steel,....)
  • Use of hot runner or cold channel
  • Number of cavities, among many other points to be considered.

New Projects
With the increase of usage of plastic materials in most diverse markets and technologies, more and more companies are looking for complete solutions for their product, focusing on their biggest goal, which is to define the design of the desired product. The complete solution consists of the evaluation of the current product and the presentation of suggestions that permeate from the possibility of it presenting surface marks resulting from thicknesses / shapes not suitable for the plastic material to be used, the most correct definition of the type of plastic material to be used , the definition of the injection mold strategy and the injection itself. This possibility to centralize all tasks in a single company that manages all the steps untill reaching the final piece has made a difference. In addition, with a technical team with more than 30 years experience following projects around the world, it has made Nord West an outstanding company in the market.

Parts for use in the cosmetic field
The market as a whole has been growing in segments that until then were not widespread such as in cosmetics, not least because the application of procedures such as GMP - Good Manufacturing Practices end up being required to meet the standards of each company. The sum of high precision injection with total process control can be a great solution for companies that wish to manufacture their products using this technique, which ends up generating a great cost-benefit ratio in the final product.
Dental Products
With the implementation of BPF - Good Manufacturing Practices in its manufacturing system, several companies have stood out in order to allow plastic materials to meet all the requirements of specific legislation in segments such as dental and medical-hospital. The possibility of manufacturing products with complex geometries and in light materials, with excellent mechanical, thermal and chemical properties has been highlighting the plastic parts injection segment for presenting an excellent cost x benefit ratio in the final product.
Optical Parts
The emerging need for solutions where only glass has been used has made plastic material developers look for alternatives with better properties that serve different market segments. The use of lenses has already been widely used in the market, but the control of the level of diopter has been the great challenge of injection companies. The excellent results in the optical area boosted the markets for visors, indoor and outdoor area lighting and even the medical-hospital segment, which also seeks fungi control over these products. The possibility of being able to achieve complex geometries has allowed a large space of plastic in this market and thus having as a final product something with a good cost x benefit ratio.
Technical Parts
In addition to the needs to use plastics for different market segments in the replacement of other materials, the guarantee of elements with dimensional tolerance in the centesimal scale (0.01 mm) is also possible with the use of more elaborated plastics, which pass from the Engineering and go to Ultra Polymers. This can be possible with adjustments in the product geometry, mold design, use of injectors and several other peripherals that guarantee the correct injection of the parts. This aspect allows a great reduction in the cost of the final product injected in plastic material in view of the possibility of numerous products being manufactured simultaneously in the same mold.
Replacement of metal parts by plastic
In the unceasing quest to reduce the final mass of the products, it has attracted the attention of different market niches, using alternative materials with less apparent density. In comparison with other materials, polymers with emphasis on plastics have been widely used for solutions in the most diverse areas. With an approximate 7 times reduction in the final mass of the plastic part in relation to steel and approximately 3 times less in relation to aluminum, products made of plastic materials not only add value in this regard, but also provide high mechanical and chemical resistance. This is possible because the increasing use of Engineering materials (PA, POM, PPO etc ...), High performance (PPA, PPS, PSU etc ...) and Ultra Polymers (PEEK, PAI, etc ...) comes allowing, together with the correct use of injection equipment and mold heating, levels that even allow the replacement of current metals with these materials. The use of these materials has ranged from small electronic components for use in printed circuits, electrical connectors, gears, bushings, accessories for general surgeries, dental implants and even components that will have longer periods within our body. The reduction in the final costs of plastic products is possible thanks to the use of multiple cavities in the injection mold compared to the machining of metal parts.
Finishing (Painting / Chrome Plating)
When you need a product with a “super-fishing” surface finish, that is, with control of surface roughness to the point of further improving the surface effect of parts that will receive painting or chrome plating, the strict control of the injection process can be the solution. In order to reduce losses in the chrome plating process, where the level of surface tensions in the product highlights problems in the final stage, the correct definition of the injection process parameters can be an interesting solution in order to obtain a final product at a lower cost.
Metal
The injection of parts with metallic finish (metallized) consists of direct injection with a special pigment based on metals, which give color and surface appearance similar to the metal referred to as standard. This process allows to achieve a great repeatability of the finishing of the parts, with reduction in the time of manufacture of the same, elimination of the environmental liability in relation to the painting process and reduction of the final cost of the products.
