What is the largest injection molding machine?
Capping that all off will be the LARGEST tonnage injection molding machine to operate at an NPE show – “The Cincinnati” by Milacron, coming in at a whopping 2250 tons of clamping power.
How much does an injection molding machine cost?
Large industrial injection molding machines can cost anywhere from $50,000 to $200,000+. These machines also come with more stringent facility requirements and require skilled labor for operation, maintenance, and monitoring.
What is capacity of injection molding machine?

What is ton in injection moulding machine?
The “tonnage” is the measure of force that is required to keep the tool closed during the injection process. This force is the main factor in determining the injection molding machine size required for producing the part.
Why is injection molding so expensive?
Since plastic products created using injection moulding are generally smaller and more intricate than those created by rotomoulding, there is naturally a higher investment of time and labour involved in creating them, which can ultimately increase the cost.
How is mold cost calculated?
Mould price=material cost + design + process and profit + VAT + tryout cost + packing and shipping cost. Usually in the ratio: Material cost: materials and standard parts accounted for 15%-30% of the total cost of the injection mould; Process and profit: 30%-50%;
How do you calculate injection mold tonnage?
What is the formula to calculate tonnage? To properly calculate necessary clamp tonnage, you must first know the projected area of the molded part/s plus any runners. Area can be calculated by multiplying length times width, A = L x W or A=πr2.
How do you calculate injection capacity?
To calculate the injection stroke or shot size, we can put all values in the formula of shot volume, i.e., Shot Volume = π x r2 x Shot Size. Here, r=1.4 and shot volume is 26.71 cm^3.
How tonnage is calculated?
tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.
How do you calculate injection tonnage?
Now you can calculate necessary tonnage based on the projected area times the clamp factor for the material used. T = A x cf. For example, the projected area of the molded part is 150 sq/in times a clamp factor of 3 (tonnage needed/square inch from material data sheet). 150 x 3 = 450 tons needed.
What are the disadvantages of injection moulding?
Disadvantages of injection moulding
- High tooling costs and long set up lead times. Up-front costs are high due to the design, testing, and tooling required.
- Part design restrictions.
- Small runs of parts can be costly.
Why are injection molds so expensive?
The main factors that influence the cost of an injection mold are the size and intricacy of the part, the material used, and the number of parts being produced.
