■ Filter Pins

■ Porous Vent ® Block Type Machining freedom No.1. Gas is released from all sides, so it is effective in any place.

■ Porous Vent ® Round Type The round material makes it easy to install. Also, the low price make it easy to try porous metals.

■ Date Marked Pin Sets Heat–resistant, with removal tap type Outside ring can also be replaced from the PL side, greatly reducing the time and effort required for replacement.

■ High Performance Swivel Lifting Eye Bolts Five times higher safety factor/high durability Bearingless prevents deformation and damage of bearings due to load.

■ Positioning Straight Pin Sets –Pin/Bushing PL Installation Type– Makes the maintenance easier because it can be installed and removed from PL side.

(Ejector Pins/Core Pins) Useful pin that allows gas to escape from the filter on the molded product surface. Special shape prevents resin inflow.

■ Roller Lock Sets –Heat resistant type– Improved from standard type heat resistant temperature 80°C to 150°C.

■ Cooling Uni-Joints –Heat resistant type– Heat resistant 180°C Joint pipe for cooling piping with adjustable pipe length.

■ Insert Blocks with Slit Vent Diffusion bonding slit structure releases more gas, faster. Excellent for reducing maintenance.

■ Thread Prevent Cap Easy to install. Effective in thread prevention after molding trials.

■ Sprue Bushings (String Eliminator Type) Essential products for stringing prevention that is used by many customers.

Depth

The nitrided depth of MISUMI's Hardness of 900HV– plastic mold ejector pin is 0.003–0.008mm (reference value) and the depth at which the hardness of steel increases due to the combination with nitrogen is 0.1mm from (reference value) than the surface. The nitrided depth of straight ejector pin is controlled by adjusting nitriding temperature and treatment time in accordance with shaft diameter size. In the case of stepped ejector pins, nitrided depth is controlled by adjusting nitriding temperature and treatment time in accordance with tip diameter (P) size. For this reason, the surface hardness of the retention diameter (D) of stepped ejector pins becomes slightly lower at around 500HV (reference value).

Normally, it is quite easy to file down an ejector pin using a regular file (metalworking file). The nitriding treatment applied to the surface of SKD61 + Nitriding makes it difficult to file down because the file does not bite as easily into the surface. The nitrided layer is several microns thick, so a little pressure should be applied to the file. ※ Most regular metalworking files have a hardness of 68–70HRC. How to measure the hardness of the ejector pin: 1) If you want to check the hardness quickly and easily, use a simple hardness check file. 2) When you want to measure hardness accurately, we recommend using a Vickers hardness tester or micro–Vickers hardness tester. Since Vickers hardness testers can change the test load during hardness measurement, they are useful for measuring objects that are small, thin, or have curved surfaces. It is suitable for hardness testing of thin cylindrical parts such as ejector pins.

One point advice Rockwell hardness tester (C scale) is generally not suitable for measuring the hardness of thin cylindrical parts such as ejector pins.

L ≦ 500 L ＞ 500 p 1 Precision

b 2 (Guaranteed Range of Base Material Hardness)

The Rockwell hardness tester (C scale) applies a large load (150 kgf) to the object to be measured with a diamond conical indenter when measuring hardness. If the object to be measured is not flat (curved surface), the conical indenter will slip and measurement error will occur, causing the meter to display a lower hardness than the actual hardness. The measurement error of this curved surface shape requires correction of the values according to the manual supplied with the hardness tester. (The thinner it is, the larger the measurement error.) In order to keep the measurement error of the Rockwell hardness tester (C scale) low, it is necessary to cut the object, make a flat part, and measure that part. Not suitable for measurement of thin plates. (Generally speaking, a thickness of at least 1.2mm is required for hardness measurement.) General guideline (reference value) for measuring cylindrical objects (curved surface) with a Rockwell hardness tester (C scale): –Approximately φ 6mm............Not suitable for measurement because of large error and difficulty in measurement. φ 6.5–9mm..............................needs to be corrected according to the manual provided with but it is said to be unsuitable due to large measurement errors. φ 10–25mm.............................Correction is required according to the supplied manual. Approximately φ 30mm............No need for numerical correction after measurement. ＊ There are models that can be changed from C scale (HRC) to A scale (HRA) or D scale (HRD) of Rockwell hardness testers, but the load applied during measurement is as high as 60 kgf for A scale and 100 kgf for D scale, so they are not suitable for measuring thin objects or objects with curved surfaces as well as C scale. ※ For details, check the manual that comes with the hardness tester.

When ejector pins are processed to determine the total length, fine, processing burring about 0.02–0.05mm (reference values) in length occurs at the edge of the tip. When this burring is removed, a slight sag results. MISUMI does not deburr the tip in order to prevent sagging. The allowable sag R at the tip of the pin depends on a variety of conditions such as precision of individual mold, characteristics of the formed object, various shape and resin type. For this reason, the sag R caused by deburring may be an issue. Use an oilstone, sandpaper, cloth, etc. to remove the burring according the precision control standards on your design drawing of the mold being used.
