How much does an injection molding machine cost?

How much is an injection molding machine? This is the most frequently asked question by customers. And in this era of the Internet, product prices are already very transparent. But in fact, consumers must first know what kind of machine they need before asking the price. The injection molding machine you purchase needs to be used to produce what product, what materials need to be used, whether the product line will be greatly changed in the future, what level of product precision needs to be achieved, etc. 

Simple plastic injection molds can cost anywhere between $3,000 and $6,000. The price for a large, more complex high-production, multi-cavity mold can cost upwards of $25,000 – $50,000 or more. Although easy to state, there are a lot of details that go into the cost of injection molding.These all directly affect the injection molding machine s price. So what are the factors related to the price of injection molding machine, and what factors are affected by it?

1. Injection unit selection of injection molding machine

Determine that a unit has sufficient volume to accept the injected injection volume. The general choice is that the required injection is between 10% and 80% of the total volume.

2. Cycle time of injection molding machine

According to the wall thickness, flow, gate thickness, ribs and flanges, determine the approximate filling, packing and cooling time, according to the height of the part (clamping stroke), core, slide valve action and the discharge of any necessary parts, determine the approximate Clamping traverse time and part discharge, which will help determine the operating specifications of the plastic injection moulding machine required.

3. Decide the required clamping force

Check the height of the part, wall thickness, material, core and projection surface to determine the required clamping force.

4. Hourly output weight of injection molding machine

Verify that the selected unit can produce the required output. The output is calculated in pounds per hour. If the selected unit is unable to meet the required output, increase the length to diameter ratio, and then review again. If increasing the length to diameter ratio is not effective, the size of the injection unit and the diameter of the screw implant can be increased, and the results will be verified again later.

5. Injection molding machine extraction rate

Using the selected mold clamping pump set and standard extruder motor of the injection unit to determine the minimum value of screw refilling or extraction and screw filling time.

6. Injection molding machine clamping speed and dry cycle pickup

Whether the clamping performance of the fixed machine is sufficient to achieve the required working performance. If greater work performance is necessary, decide whether the faster traverse speed is suitable and/or applicable, check the option of increasing the clamping speed and make a pick-up decision.

How much is an injection molding machine? I will share it with you today. After knowing the price of the injection molding machine, you should know how to choose the injection molding machine correctly? The injection molding machine uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous flow state) into the closed mold cavity, and obtain the product after solidification and shaping.
