It is cost saving to produce 2 different plastic materials or else a plastic materials with different metal inserts in your product design.

​Weak weld lines breakage in your plastic product elimination.....
Optimum type and  location of plastic injection point are analysed after Mold Flow to eliminate
@ air trapped, thus causing flashes, short shot ,internal stress
@ weld line is relocated to the biggest wall thickness  and on parting surface, thus achieving strong strength plastic functional product!

​（1） Generally, effect to the roundness by the gate type tend to be better in the following order.
​           Side gate ＜ Pin gate（double points） ＜ Pin gate （triple points） ＜ Center sprue gate
（2） Weld might influence the roundness, especially in GF reinforced grade, so take care of the gate location, try to mold under a good liquidity condition, and be careful of the mold gas vent.
（3） Deformation towards surface run out direction is often occurred by the shrinkage ratio difference between diametrical direction and circumferential direction. Other than taking balance in shape, there is a method that place a rib towards circumferential direction to strengthen the stiffness and remedy. The multi-point pin gate is relatively effective against the surface run out. 

Spring loaded pin inserts can drive plastic part out of cavity side effectively.
This will help to ensure high quality part with stable production output at low cost solution.
However, you must prepare them at tool design phase to avoid interrupting with cooling circuits as well as the most effective locations of ejection.

It is labor-intensive than two-shot overmolding, production cost per part using this technique will be higher, but it eliminates the extremely high cost and delay of producing complex two-shots mold.
If speed to market is critical, it may make sense to use pick-and-place to deliver product to market.
It reduces risk by allowing redesign of molds at a fraction of the cost of remaking two-shots molds.
Production volume-typically under 10,000parts or need to prototype design or test materials or possibility that the design will change is still  economical to use insert overmolding.
