Premium Soft Plastiс Mold Lure Making Injection Molds Fishing Lures Two Cavity Yama Senko 5''

This product is an injection mold for making the rubber worms used for fishing. This particular mold will make two of a very popular size and shape of worm. A bag of these worms retail could run up to $10 depending on the brand. But this can be made with scrap plastic or rubber. The mold works very well as long as you're careful. Making two at a time is fine for one person or one family, but it would be very difficult to mass produce these using this mold. As long as you are just making a few to try out at your favorite fishing spot, this is a very high quality product. This is also a fun way to try recycling with different materials!

first time using it and i pulled it apart and a piece cracked off of it

This is my second 5 inch senko mold from best_nj. The first one I got, also on Amazon, was aluminum, has 3 cavities, and works like a dream. It is an injection mold and works great, but it works so good in fact that I was even able to hand pour perfectly formed senkos in it.I got this one because I thought maybe I could inject both molds and make 5 baits instead of 2. But this mold does not work nearly as good. I don't know if it's the material, the design or the machining or what. Maybe there's a trick to using molds of this material vs. aluminum? It's quite conceivable I did something wrong, but the one thing I noticed right away is that this mold doesn't fit together as seamlessly as the aluminum. When you hold it up, you can visibly see daylight through the crack in the mold (see pic).I heated, reheated and injected maybe a dozen batches. I had the clamp on the one side of the mold and I experienced blowout of the seams. I moved the clamp right next to the injection hole and I didn't have any blowout. Despite this, I could not make 2 full senkos in any batch. It was like everything was cooling faster than I could inject it. The best I could do with the injector was make 1 good one. I don't know if it's the design, the material, or just my lack of knowledge or what... This is a smaller mold with fewer cavities. It should be easy to fill. But it was not. Hand pouring into their aluminum injection mold, I got better senkos than injecting into this one. It could be that I wasn't doing something right, that there's some trick to dialing this type of mold in, but I'll be honest, I would spend the extra money and get their 3 cavity aluminum mold. It costs just over twice as much but for me it worked 10 times better. I just really wasn't impressed with this mold and I won't use it. If you do choose to use this mold, be aware that the baits also cool much slower than in aluminum. The first few I pulled out were gimpy because I didn't wait long enough. This isn't like aluminum where you can pull them right out. You need to let them sit and cool a lot longer.

The mold does work to make 2 plastisol worms at a time. First use I had an issue with a little leak around gaps, but some clamps solved that problem. My syringe nozzles fit just fine. The mold seems to be made of a durable plastic. I didn't have any issues with the plastic sticking in the mold once it cooled down.It's a good starter mold to see if this hobby is for you. The metal ones can get really pricey pretty quickly.

I have always wanted to make my own soft lures, so I got this to try it out. It was a little tricky to melt the old pieces without burning them, but after I figured that out, using the mold is easy (you need to get an injector to prevent spillage). I have made several multi-colored and solid colored worms for use with ned rigs or wacky rigs and I intend to try them out today. Even though the price seemed high, I think I can make enough custom baits to compensate within a short time.

It was a little brittle but did the job. As other reviews mentioned I did get some aluminum molds that were superior quality

This is an amazing mold for being plastic. Most molds you will find are aluminum for some reason, not really needed as long as it is a good mold and can release the rubber. This is a great lure mold and well priced since it is plastic. The plastic is very dense and doesn't quite feel like plastic at all due to this density.

Got this mold so my husband could make his own baits. We still have to get the other stuff to make the baits. We are so excited to try it out.
