Countermeasure against deformation in L-shaped and U-shaped molded product
（1） At the corner part, outside cooling will be faster than the inside, so this shape tend to deform towards the
（2） Remedying by placing the gate on the corner part is sometimes possible if it is GF reinforced grade.
（3） Lightening the corner inside part is effective. Make the recess part round, and do not make the sharp
（4） If there is no limitation, place a triangle rib towards the corner. Take the triangle rib from the high location
as possible, and the thickness have to be thinner than the half of the base.
（5） If the triangle rib cannot be placed to the inside, putting a T-shaped rib on the outside of the corner is
