No Press Fits in Plastic. Looking at interference fit applications, the easiest start is the definite no: Never use press fits in plastics. Why? Two words: cold creep. Press fits rely on constant stress and friction. In steel, if you press an oversized pin into a hole, they’ll stay together indefinitely.
While it might hurt more, a wide, low-gauge needle will deliver the injection faster than a thin, high-gauge needle. Needle Length As far as the needle length, the best choice will depend on a person's size (a small child would need a shorter needle than an adult) as well as where the needle will be inserted.
Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.

Flow Lines. Description: Flow lines are streaks, patterns, or lines - commonly off-toned in color - that show up on the prototype part as a consequence of the physical path and cooling profile of the molten plastic as it flows into the injection mold tooling cavity. Injection molded plastic begins its journey through the part tooling via an entry section called a “gate.”
Injection molding LCPs causes the chained molecules to orient in the flow direction near the mold wall. It is, therefore, important to carefully consider flow patterns and anisotropy in the cavities.
