Title: Side Injection vs Top Injection
Post by: Billmo on 03/19/12 20:35 UTC: i need some help from the experts out there.. I am looking into getting a 6inch swimbait mold(for saltwater) that I would like to shot with two colors... Would i be better off with side or top injecting? I would be using a blending block to assist with the two colors...

Post by: pjmcla on 03/19/12 22:42 UTC: I would think a side injection would yield a cleaner bait. Less turns to deal with.

My bad; I thought the orientation of the bait; laterally; determined the mold's specific's. I agree that injecting straight off the nose of the bait is the best. 3/21/12. As always, Ghostbaits and Frank are dead on.

Post by: Perca on 03/20/12 03:15 UTC: Does top injection mean that the sprue opening is at the nose of the swimbait? I would think that is the better option. Or am I wrong?

Post by: Billmo on 03/20/12 13:37 UTC: Yes.. Sprue opening is at the nose

Post by: Muskygary on 03/20/12 14:34 UTC: Where is the opening on side injection then?

Post by: Frank on 03/21/12 00:53 UTC: Side injections have a 90 deg turn to enter the mold cavity. And Jim is right it will work but the top will be way more consistant. But they have to be ported one to a bait. Frank

Post by: Billmo on 04/10/12 01:53 UTC: I want to thank Jim for his advise... Top injection is exactly what I was looking.. It is a slow process making one bait at a time but with some practice they are starting to look ok...

THANKS JIM!!!

Title: Re: Side Injection vs Top Injection
Post by: pjmcla on 04/21/12 23:06 UTC: It allows a strait injection into the mold cavity. This will provide for laminates on a single cavity mold. Many side injection molds are single cavity.

Post by: ghostbaits on 04/22/12 11:10 UTC: I think the big advantage of side injection is multiple cavities in the mold. Top port only allows a single cavity unless you have multiple ports.
