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.

How to use a punching mold?

The Forming Mould is the technological equipment installed on the press for the production of punched parts. It consists of two parts, upper and lower, which cooperate with each other. A convex die is a convex working part that directly forms a punching part in a die, that is, a part whose shape is the working surface. The concave die is a concave working part that directly forms a punching part in the die, that is, apart with an inner shape as a working surface. The protective plate is a plate-like part that prevents fingers or foreign objects from entering the dangerous area of the die. The blanking plate (ring) is a part in the die for holding the stamping material or process parts to control the material flow. In the drawing die, the blanking plate is mostly called the blanking ring. Blanks are rib-like protrusions used to control the flow of materials in the drawing die or deep drawing die. The blanks can be a local structure of a die or a blank ring, or they can be embedded in the die or a blank ring. Individual parts. The pressure sill is a special name for the pressure bar with a rectangular cross-section. The bearing plate is a plate-shaped part used to connect the upper surface of the elongated die and support the stamping material. A continuous die is a die with two or more stations, and the material is fed into a station one by one with the stroke of the press so that the punched parts are gradually formed.

The punch side blade is a punch die that cuts out the feeding positioning notch on the side of the strip (belt, roll). The side pressure plate is a plate-shaped part that applies pressure to one side of the strip (tape, roll) material through spring, and urges the other side to be close to the material guide plate. The ejector is a rod-shaped part that ejects the work (sequence) or sequence material directly or indirectly. The top plate is a plate-like part that moves in the die or module, and directly or indirectly ejects the work (sequence) or waste materials in an upward motion. The ring gear is a ring-shaped tooth-shaped protrusion on the fine Punching Hole Mould or mold plate with teeth, and it is a partial structure of the punching mold or mold plate instead of a separate part. The limit sleeve is a tubular part used to limit the minimum closing height of the die and is generally sleeved outside the guidepost. The limiting post is a cylindrical part that limits the minimum closing height of the die. Locating pins (plates) are parts that ensure that the process parts have a constant position in the mold. They are called positioning pins or positioning plates because of their different shapes.
