If you know someone who's inventing some small-sized plastic gadgets, John Warobi has the ideal Christmas gift: their very own hand-operated plastics injection molding machine! The model 20A PIM-Shooter from LNS Technologies fits nicely on the kitchen counter with its compact size, and operates from standard 110V AC and consume less than 200W of electricity.LNS Technologies, hand operated injection molding machine

To maintain accurate temperature setpoints, it includes a dual-display digital temperature controller with thermocouple feedback. Despite its compact size, the model 20A is a very capable machine, according to Warobi, LNS Technologies president. The injector features a heated barrel with a manual ram and a full 0.5 cubic inch resin shot capacity. It works with steel, aluminum or epoxy molds and can operate with a variety of plastic resins including ABS, acetal, LDPE, PP, PS, PVC, and TPEs. In the field, a user would attach the PIM-Shooter (essentially an injection unit) to a drill press, tightening the shaft into the drill press chuck.

Out of necessity, comes invention

Warobi told PlasticsToday in an interview that the company's primary business is making electronic and robotic kits for schools and students. "We were trying to get a special gear part for one of our machines but couldn't get it commercially," explained Warobi.  "So, we decided to mold our own gear parts, but couldn't find a molding machine in our price range, under a thousand dollars. Since we have a machine shop and make machines anyway, we decided to make our own molding machine."

Warobi said the little machine was up to the gear molding task and could fulfill a broader role in the low-volume molded part market. "Then it dawned on us that there may be a hole in the market for a low-cost machine to do prototype parts, to test your parts in different materials, or just mold parts when you need low volumes.

"When we sell a kit to a student or a school, we include all they need so they can actually use it without buying extras.Ultimately the people that buy the molding machine will get their own mold, but at least they can try it out when they get it."

Molding your own fishing lures

LNS has already sold several of the PIM-Shooter injection molding machines, primarily to people making their own fishing lures at home. But he believes inventors are a great market to sell the PIM-Shooter into as well. "We were right about there being a niche for a machine under the one thousand dollar price point," Warobi added.

Warobi said the model 20A PIM-Shooter can be ordered through the company's web site or if you want more information about this table-top molding machine, you can write to the company at info@techkits.com.

Drying of resin pellets can

Drying of resin pellets can be accomplished quite easily by placing them in a household oven. Use a pyrex or foil tray and set a very low temperature for a couple hours. PC is usually good at 200F for 2 hours, but it depends on the amount of resin and the moisture content. If your oven has a convection setting that is even better.

I can buy a new hand molding

I can buy a new hand molding machine here in India for US$150 for a 1 ounce machine with a thermostat type temperature controller, digital would cost $50 more.
How will a home based molder dry the pellets of plastics that need drying? And you need different materials for the barrel if you are running PC and PVC.
By the way are the Rabbit machines still in production? They were tabletop machines made in the UK, plunger plasticizing with 80 mm steps in the platens to hold circular molds...

we sell mold-in brass

we sell mold-in brass inserts. We are always being asked for torque and pull out test results for these. We can't replicate the mold process so have to tell our customer to mold some in and send them to us for testing.

would this machine allow us to mold a brass insert into a test block of material?

What goes around...
I used an almost identical device for prototype parts in 1978. It worked ok but a lot of unmelted pellets came through. I had to fabricate a torpedo to drop into the barrel to force pellets out to the heated cylinder.
