. Close dimensional tolerances can be maintained. AN INJECTION MOLDING MACHINE CONSISTS OF TWO PRINCIPAL COMPONENTS. PowerPoint Presentation Plastic Injection Molding Nachiket Kulkarni 12082016 Introduction Various optical technologies have plastic components Injection molding can achieve mass production Producing components with machining process may be expensive Economical Plastic is an alternative to glass Limited by physical properties.

Therefore showing liquidity by flow length of spiral or bar flow type mold is general for practical purposes. Plastics are by far the most common materials that are produced using injection moulding. Evaluate the actual liquidity of the material when injection molding.

A plastic material usually called a resin is melted and forced into a mould via injection. The process is simple in principle. View CHAPTER 2 - INJECTION MOULDINGppt from 9871 402 at University of Akron.

Screw in full forward position. PST 371 PLASTICS FABRICATION CHAPTER 2 INJECTION MOULDING 1 LEARNING OUTCOMES At the end of this chapter student should. Controlled by shrinkage and warping.

Where is injection molding. Hence polymer fillers mold geometry and processing conditions can all influence the final tolerance. Advantages of Injection Moulding Process Minimal scrap loss result as runners gates and rejects can be reground and reused.

Parts can be moulded with metallic and non-metallic inserts. Parting planes by extending the parting line outwards 4. Injection molding machines were made in the 1930s.

It works by injecting molten materials into a mould or mold in the United States. Functional parts of the mold. INSIDE THE BARREL IS A SCREW WHOSE.

Injection Molding In Injection Molding melted plastic is forced into a mold cavity. The molded plastic part may also appear to be rust-colored. It is typically used as a mass production process to manufacture thousands of identical items.

Flow of plastic into the cavity 7. Ejection points Plastic must be ejected square to the mould Tapered sides Tapered sides allows the product to be removed from the mould. Screw moves forward for injection.

It consists of two main parts which are the injection unit that will inject the molten plastic and the clamping unit that will form the die. A thin plastic skin forms and solidifies in the mold wall. Same items can be moulded in different materials without changing the machine or mould in some cases.

This injection molding defect appears as a black discoloration on the surface of the molded part. Multiple cavity mold fix relative positions of the multiple parts 6. 1 THE PLASTIC INJECTION UNIT AND 2 THE MOLD CLAMPING UNIT.

The mould is first made by melting the plastic that is to be used. Foaming happens as the melted plastic material enters the mold cavity. Increase the melting temperature.

Once in the mould the material cools forming a component that takes on the shape of the mould cavity. Reduce the amount of release agent. This plastic molding process is commonly used in mass-production or prototyping of a product.

A TYPICAL INJECTION MOULDING SYSTEM Basic Phases in Injection Moulding Mould Closes 1st Stage Filling 2nd Stage Packing Cooling and Plasticising Mold Opens Part Ejected. IT CONSISTS OF A BARREL THAT IS FED FROM ONE END BY A HOPPER CONTAINING A SUPPLY OF PLASTIC PELLETS. When showing liquidity flow length L is used and sometimes ratio Lt between cavity thickness t will be 6 used.

THE INJECTION UNIT IS MUCH LIKE AN EXTRUDER. Inserting a small amount of nitrogen or chemical blow agent into the plastic material makes the walls thicker. Burn marks do not generally affect the integrity of parts.

Flow length will change by following factors so need to take a hold of effects that. It is then clamped under pressure by the clamping unit. The injection molding process is simple to catch up two.

Gating design where to locate the gates. Once cooled the mold can be removed. Shrinkage is of order 10-1001000 for unfilled and 1-101000 for filled across the thickness 29 Where is injection molding.

Designing injection molds 1. Injection moulding is a manufacturing process that allows for parts to be produced in large volumes. Screw continues moving forward for packing.

PowerPoint Presentation Injection Moulding Injection point The point where the plastic entered the mould. Granulated or powdered thermoplastic material is heated melted and then forced under pressure into a mould. Injection moulding is the primary method for creating plastic parts components and products.

These can be used to mass produce toys kitchen utensils bottle caps and cell phone stands to name a few.
