Ekin 120V Fixed-Platen Vertical Injection
The Ekin 120V is a fixed-platen vertical plastic injection machine. The summary lists 1200 kN clamp force and 207 g (PS) shot weight. The injection table gives an L/D of 23.6, theoretical volume 173 / 226 / 286 cm³, shot weight 159 / 208 / 263 g, injection pressure 227 / 195 / 160 MPa, screw speed 0–230 rpm and screw stroke 180 mm; the injection-rate row shows 120 g/s. Clamp stroke is 280 mm, minimum mould height 250 (350) mm, maximum opening 530 (630) mm, maximum mould size 600 × 400 mm and ejector stroke 100 mm. Pump motor power is 18.5 kW, oil tank 490 litres, machine size 2 × 1.7 × 3.9 m and weight 4.6 tonnes. The vertical layout is used for insert moulds, so inserts are placed on a horizontal plane and the machine takes less floor space than a horizontal press.
Ekin 160 Orion Horizontal Injection
The Ekin 160 Orion is a horizontal plastic injection machine in the ORION hydraulic-locking range. The page summary lists 160 tons clamp force, 300 g (PS) shot weight, 470 × 420 mm tie-bar spacing and a 45 mm screw. The specification table lists screw diameters 35 / 40 / 45 mm, L/D 22.8 / 20 / 17.8, theoretical volume 192 / 251 / 318 cm³, shot weight 175 / 231 / 292 g, injection rate 80 / 105 / 130 g/s, plasticizing capacity 12 / 15 / 20 g/s and injection pressure 245 / 190 / 154 MPa. Screw stroke is 200 mm, screw speed 0–280 rpm, clamp stroke 550 mm, minimum mould thickness 125 (200) mm, maximum daylight 675 (750) mm, ejector stroke 140 mm and ejector force 40 kN. Servo motor power is 17.6 kW, heating power 6.5 kW, maximum pump pressure 16 MPa, oil tank 300 litres, dimensions 1.2 × 4.6 × 1.9 m and weight 4.5 tonnes. The same clamp table also prints closing force as 1200 kN. Platens carry Euromap-size holes and T-slots.
Ekin 500 Orion Horizontal Injection
The Ekin 500 Orion is a horizontal plastic injection machine. The summary line lists 500 tons clamp force, 2190 g (PS) shot weight and 830 × 800 mm tie-bar spacing. The injection unit is pulled by a double cylinder on a THK linear guide; the page describes a heavy radial hydraulic motor, larger hoses and high-flow valves for charging and injection. The table lists screw diameters 80 / 85 / 90 mm, L/D 21.3 / 20 / 18.9, theoretical volume 2135 / 2410 / 2702 cm³, shot weight 1964 / 2217 / 2486 g, injection rate 384 / 465 / 510 g/s, plasticizing capacity 50 / 62 / 70 g/s and pressure 176 / 158 / 135 MPa. Screw stroke is 425 mm, screw speed 0–165 rpm, clamp force 5000 kN, clamp stroke 780 mm, maximum daylight 1590 mm, minimum mould thickness 320 mm, ejector stroke 230 mm and ejector force 130 kN. Servo motor power is 62 kW, heating 35 kW, pump pressure 16 MPa, oil tank 800 litres, dimensions 1.8 × 8.5 × 2.5 m and weight 17.2 tonnes.
Services
Barrel and Screw
Barrels and screws are listed as injection-machine spare parts in standard, PVC and bimetallic types. The standard barrel uses 8550 (38CrMoAl) nitriding steel, 96-hour gas nitriding, surface hardness 58–62 HRC and a nitrided depth of 0.5–0.8 mm. The ring, check ring and washer use 2379 (SKD11 – X155CrVMo12) cold-work tool steel, vacuum hardening to 62–64 HRC and a tungsten-carbide coating. The PVC screw uses 4140 (42CrMo4) quenched-and-tempered steel with hard chrome 0.05–0.08 mm thick at 62–65 HRC. The bimetallic barrel adds a centrifugally cast bimetallic alloy on 8550 steel, with hardness 62–72 HRC, an average of 68 HRC and an alloy thickness of 2.5–4 mm.
Special Production Machines
Ekin Makina, which has been manufacturing since it was founded, also builds special machines for a customer’s requirement. The special-production page lists an additional injection-unit application, C-type vertical machines, T-type vertical machines, L-type machines with vertical locking and horizontal injection, and micro injection machines for very small parts. The history also records a two-colour horizontal machine in 2000, a C-type columnless vertical machine in 2014, and a horizontal rotary-table, two-colour, hydraulic-lock machine in 2016.
After-Sales Technical Service
Technical service is reached at +90 212 771 11 67 or [email protected]; written support is requested through the form on the site. The homepage lists on-site service, specialist staff, spare-parts stock and 24/7 on-site and telephone service among the reasons to choose the company. The service is after-sales support for the plastic injection machines Ekin builds. Contact hours are given as weekdays 08:00–18:00 and Saturday 08:00–13:00.
