Wax Molding Tools and Procedures of Jewelry Making

IPlastic mold makingProcess of plastic mold creation is regarded concisely as plastic cutting Rubber die is widely used in the commercial heavy production due to its property of emancipate cutting and elastic any cordial of complicated mold which can be used up to 10 years once it is absolute It is not that difficult to groove a innocent mold, but one with intricate trestle needs supplementary research, patience and way Tools for making a plastic mold needs:1.Frame mold: it is frequently made with aluminum of assorted sizes, more metal materials such as steel are allowed as well2.Raw rubber: cement used at the beginning is the untried rubber without being ripened, at the situation the rubber used is of great plasticity which can be mark and combined arbitrarily Through the ripened process shapes of the mold is fixed, which is of large elasticity and toughness Expect average rubber, silicon rubber is taken as materials in ended years as well3.The scalpel: it is the prime appliance for cutting a plastic mold. Shapes of knifes can be chosen according to needs Careful urgency should be paid to the operating process due to the raucous blade4.Mold remedy pen, it is actually a special electric iron which is used to alter defects on the plastic mould5.Nozzle pocket, outlet of each mold would be not that thick, in edict to make convenience for wax injection, a special machine would be used to baldachin the side to earth the rub of bell mouth.6.Hot press, it is the salutary channel of a plastic mold With convertible temperature, there are electric heating wires at both the upper and dilute platen area, the upper manipulate plate is connected to screw perch to change require and distance between the two plates. The temperature is regularly at 140 ~150 IIWax mold makingWax molds are made on the impetus of plastic ones, the process if called wax injection. Wax which is used to cause the mold is made with waxes of different compositions to attain the needed synthetic wax of different melting point, hardness, toughness and strength General demand for all kinds of wax is curtained strength, which can be baked completely to drop no residue Wax creation can be divided into three processes:1.Wax of injection. Wax of the kindly of interest quality should be of ladylike elasticity, speedy solidification, sake fluidity, low melting spot and possible removing property from the plastic mold There are green, red and several further colors in the peddle used to spot the different property Green wax gains comprehensive application in the industry Melting body of welfare wax would be occurred at 63 ~74 , the shorten the temperature, the smaller the abridgement of the wax; once the wax is of gangling temperature, it would travel into the carves in the plastic mold, which would contain lather when cooled off due to the inhaled air2.Injecting wax The wax which is melted by wax injection device consign be injected into plastic mold and placed to be cooled off in 2~3 minutes. Get the wax mold carefully after the procedures Adjustment of the temperature is settled according to property of the wax while air obligate is adjusted according to the diameter of the mold When injecting, using two piece of aluminum or steel or organic plate clamp the rubber mould, the process would be complete by dominant the doorknob appropriately. When the register illuminate goes out, the wax mold is settled down3.Take the wax design It is famous to attain the fix spot to transact out the mould, if it is too early, the wax is not solidified yet, if too later, it would be too hardened and brittle to be feeble removed. Put the having been injected and cooled device on the bench, and then with one labourer supporting the contract die, another bended slowly to perceptive the upper one, the wax decoration would be taken out soft Small defects on the surface of the wax vanguard can be repaired slightly by supplementing or scratching methods
