Abstract

Studies was carried out to design and fabricate wood based cylindrical flange samples for the 50 tons injection molding machine from the wood fibre sample with the least lignin and hemicellulose percentage composition after alkali (NaOH) treatment.The untreated Obeche, Mahogany and Oak samples had mean compositions of 34.10±0.87,36.10 ±3.14 and 35.10±1.42%respectively for the hemicellulose and 30.20 ±1.22, 32.30±2.02and 33.20±1.55%respectively for the lignin.The NaOH treated Obeche, Mahogany and Oak samples had mean compositions of 28.10±0.53,18.22±0.31and 25, 31±2.41%respectively for the hemicellulose and 26.30±1.44,12.60±0.97and 23.20±1.83%for the lignin.After the selection of the treated Mahogany wood samples, the produced Mahogany based cylindrical flange had 40.14±1.74,75.07±3.02,25.00±2.89,55.19±1.88 and 63,22 ±3.42 MPA as mean values for impact strength, tensile strength, hardness, brittleness and flexural strength respectively.With the obtained values of the tested mechanical properties of the produced Mahogany based cylindrical based flange, the 50 tons injection molding can be operated efficiently to sustain production processes for as long as possible without failures from the flange position.
