Protolabs' process, however, usually does not support the production of contoured pins unless a customer requests it. In a traditional steel production tool it may be possible to machine the end of the pin to match the contour of a part surface that is not perpendicular to the direction in which the pin moves, producing a contoured pin. And if the surface of the part is not parallel to the flat end of the ejector pin, the cosmetic impact will be even more obvious. If the part surface at that location is textured, the smooth surface of the pad will be apparent. To be effective, the pins need a flat "pad" to push against, and the surface of the pad must be perpendicular to the direction of pin movement. In Protolabs' process, the ends of ejector pins are flat and perpendicular to the direction in which the pin moves. Softer resins may also require the use of more or wider pins to spread force and prevent puncturing or marring of the cooled plastic. Some resins are "stickier," requiring more force for release from the mold.
Resin choice can also affect pin placement or size. Factors like draft and texture of sidewalls and depth of walls and ribs can increase the likelihood that areas of the part will cling to the mold. Obviously the shape of the part is one (see example in illustration). In the comments section below, let us know what you would like to know about the phone.Protolabs uses round ejector pins, and their placement depends on a number of factors. The smartphone is available in two colour options Nordic Blue and Dusk – which is a brownish hue and has a recommended retail price of Ksh19000.Ĭheck back for a detailed review once we conduct a thorough assessment of the Nokia G21. Additionally, the G21 which was announced and launched in February this year will have three years of security updates that are scheduled monthly.
#EJECTOR PIN UPDATE#
It comes pre-installed with the Android 11 operating system with a maximum update to Android 13. Without the expansion, the phone has two different storage pairing profiles of 64GB storage with 4GB RAM and 128GB with 4GB RAM. The variant of the G21 available in Kenya comes with the option of dual nano SIMs and a dedicated slot for storage expansion of up to 512 GB via a microSDXC memory card. This should excite users who prefer longer stints of use between charges. To juice it up, the phone has a fast charge capacity of 18 Watts. Powering the G21 is a Li-po 5050 mAh non-removable battery on paper, and has a standby time of 72 hours. This is a 20:9 ratio with a pixel per inch density of 270. The 6.5-inch screen takes up approximately 82 per cent (screen-to-body ratio) of the G20 and has a 720 by 1600 pixels resolution. The bottom edge has the stereo speakers with OZO playback, a second microphone for phone calls and the USB Type C 3.0 charging port. The top edge of the G21 features a 3.5 mm jack and a microphone for ambient noise. To add to the already wide 1.8 aperture of the main camera is a LED flash for that extra illumination.
The trio of cameras at the back boast a main 50 mega-pixels camera with a 2 mega-pixels macro camera and another 2 mega-pixels depth camera. The front-facing camera is a wide-angle 2.0 aperture 8-megapixel shooter which also captures 1080 progressive scan resolution videos at 30 frames per second. Its textured polycarbonate casing provides that sense of security with minimal chances of accidental drops.Ī total of 4 cameras, one at the front and three at the rear, give users the opportunity to capture memorable moments in photos and videos vividly. With its width of 75.9 mm, length of 164.6 mm, a height of 8.5 mm and a weight of 190 grams, the smartphone feels comfortable in hand. The Nokia G21 smartphone is surprisingly light considering the hefty real estate the device takes up.
