What Is The Average Cost Of Injection Molds?
Plastic injection molds are usually priced between 1000 and 3000 USD. For larger or more complex products, the price may be higher.
The injection molding process is a manufacturing method that produces plastic injection-molded parts. This manufacturing process is popular because it’s efficient and can quickly produce large quantities.
A high-quality injection mould is necessary to make high-quality parts out of plastic. An injection mold’s cost can vary depending on many factors such as the material used, its complexity, and how many cavities it has.
This blog post will take a closer look into the factors that influence the price of injection moulds and how to get the best deal.
What are the costs of plastic injection molds?
Injection mold costs include design and raw material costs as well as manufacturing costs.
a. Injection mold design costs include the cost of preliminary communications. Design work includes CAE analysis, mold structure design, and 2D drawings.
b. The raw material price includes standard parts, steel, and the die holder for the part of the fixed or moving die.
c. The mold manufacturing costs include the cost for the machining process as well as polishing, mold fitting, and mold trial, as well labor costs.
d. In general, the design costs account for around 12% of total injection mold costs. The raw material accounts for 30%-40% and manufacturing is about 30%-55%. Tax,overhead, and other 23%. Assembly, heat treatment, mold testing 9%. Matching 19%.
What is the difference between injection molding and injection mold?
An injection mold is used to produce plastic injection molding products. It also gives plastic products their exact structure and dimensions.
Injection molding allows for the mass production of complex shapes through an injection mold.
In other words, heat-melted plastic is injected in the mold cavity under high pressure using a plastic injection molding machine. The plastic is then cooled and cured to create a molded product. Injection molding is a type of injection and molding.

What are the main components in an injection mold?
First, we must know what components make injection moulds. This will allow us to understand the impact on cost.
According to their function, the basic structure of an injection mould can be broken down into seven parts: pouring system, pouring mechanism, guiding mechanism and ejecting mechanism. There are also lateral and core extraction mechanisms, cooling and heating systems, exhaust system and cooling system.
A. MOLDING PARTS
It refers specifically to the components that make up the mold cavity.
B. POURING SYSTEM
It is the plastic flow channel that runs from the injection molding machine’s nozzle to the cavity. Common pouring systems are composed of a main stream channel, diversion channel and gate.
C. GUIDING MECHANISM
It is responsible for positioning, guiding, and bearing certain pressure. This ensures that the closed dynamic or fixed molds are accurately closed. The mold guiding mechanism includes a guide pillar, guide sleeves or guide hole (directly open on the template), positioning cone and others.
D. EJECTOR DEVICE
It is used primarily to eject parts from injection molds. It consists of an ejector tube, push plate, ejector plate or ejector fixing plates, restoration bar, pulling bar, etc.
E. LATERAL PARING AND CORE EXTRACTION MECHANISM
Its function is to remove the lateral convex mould or the lateral core. This usually includes oblique guide pin, bent pin and oblique slots, wedge tight block, wedge slot, oblique slider, and oblique slot.
F. COOLING & HEATING SYSTEM
It regulates the temperature of the injection mold process by cooling the system (cooling hole, cooling tank or copper pipe) and heating system components.
G. EXHAUST SYSTEM
It is responsible for removing the gas from the cavity. This is done primarily by the exhaust slot with other components.
