The Punching Mold is an accessory corresponding to the punching machine. The workpiece is plastically deformed under the combined effect of the punching machine and the resistance of the die to complete the processing process. The punching die is an essential part of the punching process. The accuracy of the punching die is largely determined by the accuracy of the workpiece machining.
The punching die is the upper half of the whole pair of punching dies, that is, the punching dies mounted on the slide of the press. The upper die seat is the uppermost plate-shaped part of the upper die. When the workpiece is close to the press slider, it is fixed by the die handle or directly with the press slider. The lower die is the lower half of the whole pair of dies, that is, the dies that are installed on the work surface of the press. The lower mold base is a plate-like part on the bottom surface of the lower mold and is directly fixed on the work surface or the backing plate of the press during work. The blade wall is the sidewall of the cutting edge of the punching die hole. The edge slope is the slope on each side of the blade wall of the die cavity. The air cushion is a dome with compressed air as the motive force. See “Bouncing Device”. The back-side clamp is a part that supports a unidirectionally acting punch from the other side of the working surface.
At least to some degree, asking what plastic injection molds cost is a lot like asking, “How much is a car?” Will your mold be a Pinto or a Porsche? And don’t forget that the price of a mold is just the beginning. To determine overall plastic injection molding costs for any project, you have to consider raw material, operation, and repair costs later down the road too.
The cost to make a plastic injection mold
The determining factors in the cost of your Drawing Mould are a combination of the part size, complexity, material, and anticipated quantities. For instance, if you wanted 1,000 washers per year, we would recommend a single cavity mold, meaning it makes one washer per machine cycle. In that case, the mold would probably be $1,000-2,000.
However, needing 100,000 Xbox controllers every month is a different story. For this requirement, we would build a 12 cavity hardened “family” mold which would make four Fronts, four Backs, and four Button Trees every cycle. Of course, this type of mold comes with a cost. You’d better have $60-$80,000 or more to invest!
These examples are extreme, but they illustrate the range of costs to anticipate. Your particular part will most likely fall somewhere in between that. At Rex Plastics, our molds average around $12,000.
