In-house development of material blend
■DaikyoNishikawa carries out research and development regarding material blending for optimal attributed products, which also have best suited characteristics for the new manufacturing method of mass production.
■This in-house blending recipe makes it possible to reduce cost and black box the know-how.
Development of material blend and in-house compound
Product design process
Based on design data received from the customers, we create product designs with a balance of marketability, performance, cost, productivity, and other factors in order to provide products that satisfy the customers.
Digital development centered on core CAD (NX/CATIA) for high quality and short delivery times
Key advantages of DNC (DaikyoNishikawa) design
1.Achieves ultra-short delivery times.
For example, we have completed the process from bumper order to design, prototype, and mass production in only 10 months.
2.Capable of multi-perspective development of automotive plastic parts.
By making use of the expertise which we have developed through the development and production of all kinds of plastic automotive parts, including interior, exterior, body, chassis, and power train parts, we are able to work from multiple perspectives to achieve the optimal product design.
Rigidity and thermal deformation analysis
We evaluate the product's basic rigidity and ensure that it satisfies the required performance. We also measure the effects of heat on the product, for a high quality product design.
We evaluate vibration characteristics and incorporate the results into our designs in order to reduce the effect of vibration on people and products.
Shock analysis * Figure 1
We analyze shock performance which can affect people and products, and create high-performance product designs with a higher level of product safety.
Air-conditioning analysis * Figure 2
We predict the flows of air inside the passenger compartment and raise the air conditioning performance in order to ensure heating/cooling performance and forward visibility.
Resin flow and warpage analysis
We analyze the filling, pressure hold, and cooling stages that make up the molding process for thermoplastics, and carry out studies for the creation of a highly efficient process.
We also predict the warpage deformation that will occur after molding.
Blow molding analysis
We analyze all stages of the extrusion blow molding process, from Parison extrusion to expansion.
Check reliability with which the product can withstand the envisioned harsh use conditions such as resistance to heat, cold and climate.
Check durability with which the customer can use the product comfortably for a long time, such as through vibration durability, stiffness and abnormal noise evaluations.
Safety checks at the time of a crash to ensure safety for a vehicle's occupants and pedestrians such as through passenger-side airbag deployment and head impact.
Head impact tests
We perform head impact tests with additional consideration for secondary impacts after an accident or other collision. These tests evaluate head protection performance by striking a piece of styrofoam made to model a human head against the main instrument panel parts in order to verify impact safety.
Our vibration tests reproduce the actual vibration environment in order to check the conditions of products installed on the vehicle during driving. This experimental evaluation verifies the high levels of performance and quality, for greater reliability.
