Pet Preform Manufacturers Design Mold Uniform Wall

Uniform
Wall or Gradient: As mentioned above, a uniform wall is the target that a

 should
aim at when designing a part. Uniform walls ensure optimal, unforced material
flow while also helping to ensure even cooling (discussed later). If it is not
possible to design a part with a uniform wall, you must ensure that the
thickness is gradually transitioned rather than abruptly transitioning the
thickness. A good rule of thumb is to multiply the thickness change you need by
three and then apply the transition over the length of the part.

Rounded
corners and no sharp corners: If you suddenly change the thickness, you end up
with a flat wall and sharp corners that cause this change. The acute angle
problem with injection molded parts is that thermoformed plastics are
difficult—and virtually impossible—to completely fill an area with this shape.
In addition to the gradient of the thickness, avoid sharp angles at the corners
of the part as much as possible. In addition to molding problems, acute angles
retain most of the residual stress of the finished part, making them more
susceptible to breakage.

Instead,
the corners should have a radius applied—in other words, they should be round.
It's best to round them as much as possible while still maintaining the desired
shape and function of your workpiece, but as a general measure, keep the inner
radius of your corners at 0.5 times the wall thickness they appear, and the
outer radius is the wall thickness. 1.5 times.

tracking them, you and your products can be successful.
