In an attempt to improve the accuracy and efficiency according to the requirement. No work is done in proper designing of special manual machine, these days, rather rule of thumb prevails. To keep pace with company demands improvement in the design of the manual press is needed. So I worked to improve the designing of the machine for getting the best results by designing the balls of cast iron that provides appropriate pressure to stop fluctuation in size of components. The specific dimensions of the press machine is as Improvement in design of the manual small press machine for job under 900mm2 area X 1mm thickness in grade 304. Though in extreme case it can work even on 2.0 mm thick stainless steel of specified area, without any problem.

INTRODUCTION extent if not one hundred percent. This has There is an increase in technological methods been one of the major problems of companies in all daily activities in the industries. This is nowadays because their equipment and done to improve the quality, efficiency and customers to buy the new products anytime cost deduction of a particular product. Many they are released. This was the reason to manufacturer companies try to be up-to-date examine equipment modification machines in their products’ improvement with thinking are very expensive and high maintenance the effects on their customers. Although it is and the manufacturers should not expect the. good for customers side to have the latest Fly Press version of particular products but if the interest of their valued current customers is Fly press is a press machine which is used to be put into consideration there should be to make some press and operations a stand-by solution to their existing products in the industries. The main function of press improvement to suit the latest version to some machine is to punch or press the metal sheet

Res. 2014 Vivek Sharma et al., 2014 or the specific portion of the assembly/work A common problem that we are going to piece which we are going to make with the face with the working with fly press is that help of that press machine. The basic picture the weight of the flywheel is fixed no change of the fly press machine used till now is can be done with that weight. Because the shown. This type of fly press machine is used whole fly press is made up of by .So for the different purposes in the industries like the rigidity of the machine is comes in a form joint of the door. This press machine is widely of a big problem regular product by the used in the small scale industries where the customer. demand of special item for the product is Suggested Solutions changed time to time with the main product. 1. Buying a new attachment for the If the new machine is purchased for each odd different product to be assembled. (High item than the regular demand, the cost of that cost) odd item is so high that the profit level of 2. Managing the old one with help of some industry is down. So, after study the whole supports (Low efficiency and cost) working of the industries I suggest an idea to solve the problem up to some extend by 3.

Another problem that the worker has to LITERATURE REVIEW face while using the hydraulic press machine The press machine Gutenberg (Johan is that he must needed to trained with that Gensfleisch) a German invented in 1400 hydraulic machine and also know the whole was modified one from a wooden screw type working process with the all working press machine for squeezing olive oil and conditions of electricity fluctuation, grapes. This was exactly the root of the screw temperature etc. all this make the worker so presses and all press (, ) much costlier that the rate of that specific machines, stamping inked print boards onto product is also so much high that the working sheet with the screw. This is the type of with that is not suitable for the owner. machine to apply static pressure.
