*Exact material was not characterized in MoldFlow, therefore a material with similar properties was used. Material accuracy can have significant results on the outcome of the flow analysis. If the exact material is required please provide a .udb file of the material which can be imported into Moldflow . This file can most often be obtained from your material supplier.

It is understood and agreed that by accepting this proposal, it is the responsibility of the customer to interpret and evaluate all results from engineering calculations. Not included in this proposal are stress concentration factors due to manufacturing techniques, residual stresses due to molding and forming, and stresses due to other loadings not included in the proposed analysis. The use of engineering analysis and design tools in the design of injection molds requires engineering judgment and equipment field experience, as well as accurate understanding of manufacturing and operator factors. Engineering calculations are but one factor of many to be considered in the design and manufacture of injection molds. Thus, all decisions regarding the design and manufacture of injection molds and injectionmolded parts are the sole responsibility of the customer. Since the customer is responsible for the decisions effecting the design, manufacture and application of its products, it is understood and agreed that INCOE Corporation and its consultants are not responsible for any losses and/or damages to the customer, its customers, or any other third party resulting directly or indirectly from the use of the engineering work product defined in this proposal. The customer agrees to defend and hold INCOE Corporation and its consultants harmless in any event.
