I think Tom is the one who hand pours the heads of the smaller baits by using a tea spoon. It seems like that would be easier and faster than using a lami plate. I'm curious what you guys think.
The same principals apply as if you were comparing hand pouring to injection. It may vary by individual, but I can't hand pour 10 cavities as fast as I can inject them, especially if it is a single injection into 10 -12 cavities. With the lami plate all you do is clamp it on, inject it, put a finger on each side of the runner and pull the runner out (like a zipper). Then close the mold and inject again. You get a perfect laminate with almost no rejects.
I would summarize the options like this:
Blending block - fastest, little waste, moderate level of skill
Lami Plate - faster than hand pour, no waste, same level of skill as regular injecting
Hand pour - slowest, no waste, some skill
With that said, if I can hand pour a laminate without slopping plastic on the sides that's what I normally do. I find the lami plates very useful on very small baits, carrots because of the taper in the tail, wutz-its (hook slot and tail), etc.
Feel free to disagree or share your personal experience.
