Strength of DaikyoNishikawa

Resin Blend Technology

Depending on the place and applications to be used, required performance and attribution for resin can vary greatly.

For example, the resin components used in the engine bay must have high functionality to withstand high temperature, vibration or the denaturalization by oil.
On the other hand, the exterior parts need to withstand not only intense temperatures and strong shock but also asked to maintain a long period of time a beautiful shape and color. For the interior parts, it is necessary to achieve both comfortable feel, luxury and safety.

DaikyoNishikawa has worked on developing wide range of products to meet the car manufacturers' request of right resin in the right place. "From upstream to downstream", DaikyoNishikawa carries out from research and development of blending resin material to manufacturing molded products with stringent quality verification in integrated process. Its craftsmanship backed by the accumulated data and know-how has been utilized to produce every resin products.

Weight Cutter

Weight cutter

It is essential to reduce weight for the improvement of the automobile performance such as "run", "turn", "stop" as well as energy saving.

While the specific gravity of iron alloy is approximately 7, resin is about 1.2 to 1.5, which means it is feasible to make lighter made of resin product when compared with the counterpart of iron alloy in the same shape.

DaikyoNishikawa, to pursue the possibility of resin, has been promoting the development of strong, tough and light weight product. It achieved to reduce the thickness of the bumper up to 2 millimeters. To achieve the weight and improve fuel efficiency, as well as reduce the thickness of the bumper up to only 2mm without any sacrifice in rigidity and safety features. Another excellent example will be found in engine cover with the foam molding technology that reduce not only weight but also noise in the engine bay.

Replacing Metal with Plastic

Automobiles consist of variety of aggregates such as iron, aluminum, magnesium, glass, cloth, leather, rubber, and resins. Collision safety and comfortable ride implementation is often accompanied by weight gain that gives negative impact for dynamic performance and energy efficiency. In order to achieve weight reduction in grams consistent with maximum safety features, making use of resin's potential will be one of the most appropriate solutions.

History of DaikyoNishikawa is also the history of "replacing from metal to resin".
Parts in the engine bay as intake manifolds, oil strainers, engine covers are some examples that DaikyoNishikawa replaced steel with plastic first in the industry. Another achievement is car body shell like back doors, fenders, front hoods, which greatly contribute to weight loss of automobile. Today, resin is used even in structure part. DaikyoNishikawa has made engine shroud, believed for long it should be metal to support heavy radiator.

These cars, equipped with DaikyoNishikawa parts, are already on the street round about.

Engine oil play an important role on running engine smoothly and stably. Oil strainer is one of the key parts to manage the oil circulate and filter impurities.

As built inside of the engine, it is unnoticed but reliable operative behind the scenes, still engineering effort of DaikyoNishikawa has changed material of the oil strainer; made of resin from metal.

Since this part is always exposed to high temperature, vibration, and oil, conventional metal made oil strainer was common sense among the industry. DaikyoNishikawa has developed resin made oil strainer taking advantage of the resin characteristics by optimizing parts shape to improve lubrication performance of the engine, and contributes to weight reduction.

Since it was adopted in production vehicles in 1996, now plastic oil strainer of DaikyoNishikawa has been installed in any of the models of all of the domestic automobile manufacturers. This approach has resulted DaikyoNishikawa to gain top share in the field of plastic oil strainer*.

Commitment to Finishing of Parts

Commitment to finish

Automotive interior parts that the driver and passengers touch, feel and see, must to have sophisticated finish with soft in feel and luxury, at the same time the ability to protect in case of emergency.

DaikyoNishikawa, sticking to the finishing of interior parts, has a variety of instrument panel (dashboard) manufacturing methods. It has wide variety of product line-up from urethane injection molded product that is used in luxury cars, good soft-feel painted tactile in injection molding product used in mid range cars, and standing colored molding product for entry model range cars. In addition, hydraulic transfer paint, film insert, hand-wound decorative parts will meet car manufacturers' diverse needs.

DaikyoNishikawa's comfortable and safe interior parts are produced with its elaborate persistence in finishing.
