Bercak merupakan cacat pada permukaan plastik hasil proses injection molding. Penyebabnya adalah adanya kandungan air yang terperangkap. Penelitian ini bertujuan menentukan berapa lama durasi waktu pengeringan untuk menghilangkan bercak. Caranya dengan menghitung waktu sejak pemanas hopper dinyalakan sampai material plastik digunakan. Sebab satuan waktu merupakan parameter paling mudah dikontrol oleh pekerja (operator) mesin injeksi. Penelitian dengan cara melakukan proses cetak plastik menggunakan mesin injeksi pada material acrylonitrile butadiene styrene (ABS). Cacat bercak diamati pada permukaan produk hasil cetak. Pengamatan dilakukan secara visual langsung saat produk keluar dari cetakan. Produk yang baik adalah permukaan halus tanpa bercak. Pengeringan terbaik diperoleh pada suhu 84֯C selama 4 jam. Pengeringan kurang dari 4 jam pada produk masih timbul bercak, pengeringan diatas 4 jam merubah warna karena pigment terbakar efek dari terlalu lama dipanaskan.

“…So, the optimal setting of the production process is a crucial factor that affects the quality, cost and productivity of injection moulding. [3,4] Studied component for injection moulding was intended to serve as a stopper in the automotive spotlight and it should be made from material Dyblend from German company Hoffmann + Voss.…”

The article deals with the research of the pressures originated inside the cooling system and also in the mould cavity during the injection moulding process. The simulations were realized for three designed types of running system and for four versions of cooling system. 3D model of the mould was created in Autodesk Inventor Proffesional software and then solidification of material was simulated in Autodesk Moldflow Insight software. The results were compared and the best version from the view of pressure was manufactured and placed into the injection moulding machine Arburg Allrounder 320 C.

“…After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mouldmaker (or toolmaker) from metal, usually either steel or aluminium, and precisionmachined to form the features of the desired part. [1,2] Injection moulding is the most common modern method of part manufacturing today. It is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.…”

The article deals with the mould running system design. The goal of design presented in the article was to propose the mould form so to be achieved the minimum waste for selected component. Studied component is intended to serve as a stopper in the automotive spotlight. The waste is considered the material that solidifies in the volume of plastic inside the running system. 3D model of the mould was created in Autodesk Inventor Proffesional software and then solidification of material was simulated in Autodesk Moldflow Insight software. There were designed three alternatives of running system at which the waste amount was evaluated. On the basis of the best solution, the real form was manufactured and placed into the injection moulding machine Arburg Allrounder 320 C.
