Production rate of injection molding machine depends upon cycle time (total time that machine takes to produce a product in one cycle) and the number of cavities. For calculating cycle time, you must consider time for each phase that machine takes in one cycle. That phases are:
- Mold closing / clamp
- Filling
- Pack and hold
- Cooling and Recovery (40-60% )
- Mold Open
- Ejection Add time taken by each phase. For example, this time is 15 seconds and the number of cavities are 2. So the production rate is 2 finished product per 15 seconds. You can increase your production by decreasing the cycle time. You can decrease cycle time by following some points:
- Keep wall thickness to minimum required for your product
- Ensure your machine is fine-tuned
- Ensure proper cooling system, injection pressure and injection speed is applied.

What is injection molding?
Injection molding is a commonly used manufacturing process for the fabrication of plastic parts. the injection molding process need injection mold and injection machine.--------------------------------------------------------Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.the following is a photo of the injection molding process:http://www.vulcanmold.com/article/Plastic-Injection-molding-process.htmlA Hollow mould is made from steel in several parts. when the mould is all together the hollow within it is the same shape as the object you wish to produce. The mould is water cooled to keep its temperature under control. molten plastic is forced into the mold at high pressure. it is left to cool for a specified period of time, then the mold is pulled apart in such a way that the object falls out of the mould and the whole thing starts all over.
What are the Main parameters that affect the injection molding process?
Following parameters affect injection moulding process. 1) nature of material (type of plastic) 2) rate of injection 3) size of the component being moulded 4) efficiency of machine 5) type of cooling method adopted 6) curing time in the mould
What is molding shrinkage?
tolerance that is needed to keep before the moulding is produced. As part shrinks in size after it is cooled.It depends from plastic to plastic as every plastic has different property.
What machines are used to make iphones?
The production of iPhones involves a variety of sophisticated machines, including CNC (Computer Numerical Control) machines for precision machining of metal parts, automated assembly lines for assembling components, and robotic arms for tasks like soldering and placing components. Additionally, specialized equipment is used for testing and quality control to ensure each device meets Apple's standards. Other machines, such as injection molding machines, are used to create plastic parts, while advanced manufacturing technologies like laser cutting and etching are employed for finishing touches.
What is an injection mold tool?
An injection mould tool is the tool that a material is injected into to make an injection moulding. Typically this is a thermoplastic although other materials can be formed using injection moulding. The rest of my answer relates to plastic injection moulds as this is my area of expertise. Mould tools are pretty costly precision machined items. As well as machining out the form of the component that is required (with a shrinkage factor as plastic shrinks after it is injected into the tool) they also have to include some form of ejection system to enable the part to be removed from the mould (typically an arrangement of pins that are moved by a hydraulic action on the injection moulding machine) and some method of heating/cooling to control the temperature of the mould (typically drilled channels in the tool to allow water or oil at a preset temperature to pass through the tool although electric heaters can be used (an inferior system in my opinion but can be cheaper)) Depending on the geometry of the part to be made tools can incorporate various "actions" which are basically bits of tool that move either before, during or after the tool opens. These can either be powered by hydraulics or by the movement of the tool as it opens. Tools can be made from Aluminium for low volume or prototype moulds, pre-toughened steel (P20) for mid volume (up to a few million parts)or hardened steel. In reality the choice of tool material is largely dictated by the choice of plastic, glass filled materials and high temperature materials tend to be very aggressive and a P20 tool may only last for a few hundred parts with the most aggressive materials.
Where can I learn about plastic injection mold?
Plastic injection molding is a complex form of molding that uses plastic pellets and you heat them into a desired shape. Plastic injection molding can be very expensive when purchasing tools.

How does injection molding work?
Injection molding is a process in whih the material normally plastic,is injected into a mold to produce a componenet.
What are some facts about injection molding?
Injection molding is the manufacturing process for producing parts from thermoplastic and thermosetting plastic materials.
What is the procedure called that allows plastic injection with custom molding?
The procedure that allows plastic injection with custom molding can be found on many a website. A simple search may turn of thousands of results and methods on plastic injection.
What is the Benefit of Plastic Injection Molding in Automotive Manufacturing?
Plastic Injection Molding continues to advance as the new technology emerges and it brings new opportunities in automotive manufacturing. Automotive Injection Molding reduces the weight of all vehicles, which increases fuel efficiency without sacrificing the power. The less weight an engine must move, the more responsive the engine becomes for driver. Plastic injection molding lowers the total weight, hence fewer emissions. With so many interior and engine parts currently made with plastic injection molding processes, the weight of the largest cargo hauling vehicles is dropping increasingly.For more information about plastic injection molding and medical injection molding, please visit advancedplastiform
What are some practical applications for injection molding processes?
Virtually anything made of plastic can be made by injection molding. Everything from plastic cups to car parts and aircraft parts are made by this process.
Can PET be used in extrusion blow molding?
Hey there,Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.- noizyoyster.com
Where can people find information on injection molding companies?
These are also called plastic molding companies, there are several in the united states. Try some of these websites www.rexplastics.com/, www.zycon.com/Products/Plastic-Injection-Molding.html.
How does ceramic injection molding work?
Ceramic injection molding is similar to plastic molding. It uses a machine that heats ceramic at a very high temperature. It will melt it than it will heat it to make it stay.
What is injection molding simulation and how does it work?
Injection molding simulation is the process of modeling the plastic injection molding processes using computer software.The software allows the user to input various injection molding parameters such as material type, melting point, gate size and location, runner size and location, and part geometry.
What is the Process of making plastic articles by injection molding machine?
extrusion moulding
What do you get out of injection molding?
Plastic injection molding covers the fields of aerospace, auomotive, telecommunication, home appliance&industrial components and others.For eg: the cup holder in cars, plastic electronic enclosure, plastic furniture, door handles, ect.
