● Dimensions when setting
Match mark
When assembling, if the matching taper is large, it may be necessary to adjust the height of the taper so that they fit more tightly, but if the matching taper is small, it is necessary to take sticking of the pin into consideration. At 1°taper (also 3°taper in some cases), sticking can be avoided by setting them slightly afloat as shown in the figure on the left. When the angle is small, the creep of the height (a in the left drawing) against the width (b in the left drawings) is also small, so there is no need to worry about positioning inaccuracies.

• There is a match mark on the 'MISUMI' logo side, facilitating position alignment. • Set the blocks so that the 'MISUMI' logo is visible from outside of the mold. E TBS must be used in set combination and direction being preset upon delivery. E VTBS has only the 'MISUMI' logo. It does not have a match mark.

＊ Arrows indicate direction of thermal expansion
■ The tapered block sets are capable of offsetting the plate's thermal expansion caused in high temperature molding processes for thermosetting resins, etc., thereby maintaining positioning accuracy. The pin type positioning method cannot thoroughly absorb thermal expansion when it takes place in directions as shown in the figure on the left. The block type will be unaffected if the groove direction is in parallel to the directions of thermal expansion as shown in the drawing.
