Below are some examples of our work. Click thumbnails to enlarge. Injection Moulding. Injection Moulding (or Molding to use the US spelling), along with extrusion ranks as one of the prime processes for producing plastics articles. It is a fast process and is used to produce large numbers of identical items from high precision engineering components to disposable consumer goods. Contents. 1. Typical Material Used. Typical Products Produced. Comparative Production Costs For A Typical Componentclick here to view larger image. Typical Material Used. Most thermoplastics can be processed by Injection Moulding. The table below lists some of the commonly used materials: Acrylonitrile- Butadiene- Styrene ABSNylon PAPolycarbonate PCPolypropylene PPPolystyrene GPPSInjection mouldings count for a significant proportion of all plastics products from micro parts to large components such as bumpers and wheelie bins. Typical Products Produced. Power- tool housing Disposable razors. Electrical Switches Crates/Recycling boxes. Automotive dash boards Television Cabinets. Drug Inhalation Units Automotive bumpers. Wheelie bins Syringes. Telephone handsets. Washing- up bowls. DVDs. Bottle Lids/closures. Battery Casings 3. The Process. The animation linked from this page provides a strong visual description of the injection moulding process. The essential elements are as follows: Material is introduced into the injection moulding machine via a Hopper. The screw action also provides additional heating by virtue of the shearing action on the polymer. The polymer is injected into a mould tool that defines the shape of the moulded part. It should be noted that, whilst in the animation the flute pitch of the screw is shown as constant along its length, in practice it varies considerably dependent upon the polymer being processed. In particular the root diameter increases from hopper to nozzle to provide compression to the melt. Variants of the injection moulding process include multi- shot (or 2. K moulding) (where different materials are injected into the same mould), insert moulding (where metal components are incorporated), structural foam moulding (where the material is foamed to reduce density) and assisted moulding (where gas or water are incorporated to reduce wall thickness). Size of Machine. On most machines the mould is held closed by a combination of either a Toggle clamping system that utilises a relatively small hydraulic cylinder or by a Direct Lock system that applies pressure directly using much larger diameter cylinder or combination of cylinders. The force generated is known as the Clamping Force, and is typically measured in either metric tonnes or in kilonewtons (KN), the conversion rate being ten 1. KN to one metric tonne. VECTOR. In the case of a Direct Lock machine, figures are the same as for the Clamping Force. To counteract the injection pressure, a moulding with a large surface area will therefore need a machine with a higher locking force than a moulding with smaller surface area. Other factors such as a thin wall section can also require a higher Locking Force than typical, this being to counter a higher injection pressure being required to fill the mould. There is however a direct correlation between the Clamping / Locking force of a machine and both its physical size and purchase price. Machines can be specified with a choice of injection unit size, smaller injection units providing better accuracy if relatively small components are being produced for the size of machine. There is however a proportional reduction of the maximum injection pressure that can be generated. Computer Controlled. Modern day injection moulding machines are controlled by a built- in computer. Acting on sensor fed information, it controls all the actions of the machine and ensures consistent output and shot to shot quality. Contact A Moulder.
