The machine
How it works
Pro-Tocast™ is a rotocaster—a rotational casting machine. Mount your mold, pour in resin, and rotate so the material coats the walls. Hollow props, toys, and parts, without print-layer texture. Krimplewips customers will recognize the same design; we have just brought sales home to the shop.
Nearly ten years on the bench. Thousands out in workshops around the world. Built to order, shipped worldwide—email for a quote outside the US.
Prop shops, garage kit builders, small studios, surgical teams making prosthetic forms—you bring the resin and the plan; we bring the machine.
Bench scale, built to order—workshop tools, not factory glass rotators or warehouse fulfillment.
For your shop
Workshop price, not factory price
Prop-shop and industrial rotocasters—usually steel or aluminum, built for factory scale—are commonly listed from about $2,500 to $13,000 USD. Pro-Tocast frames are hand-built from wood in our shop, run $139.95–$374.95, and ship worldwide.
We build for benches, garages, and small studios: hollow resin casts, props, and kits—not warehouse rotomolding lines. Every machine is cut, fitted, and tested here. After nearly ten years and thousands shipped, we still haven't found another shop hand-building wood rotocasters at this scale and price—if you know of one, we'd like to hear about them.
- IDM Imagineering — 16″ manual rotocaster (UK) — listed around £2,495
- Mannetron — 3′×4′ rotational casting machine — listed around $12,900
Compare plate size, motor option, and mold weight when you shop. DIY kits and industrial molders are a different category.
In the shop
How we build
Frames are SPF and white wood. We cut and shape the wood and print the plastic parts here. Motors, hardware, and the rest are chosen for the job and fitted in the shop—this is not an off-the-shelf kit with our name on it. Roughly three to four hours from lumber to a finished machine, each time.
On the bench
The gear ratio took years to get right—smooth rotation you can actually control at bench scale, without fighting the crank.These are workshop tools, not medical devices. You pick your materials and how you use them.

What people say
A decade of orders through Krimplewips on eBay—and now direct from the same workshop.
- ★★★★★
The product is well built, the delivery was faster than expected and intuitive to assemble & adjust.
- ★★★★★
Works like a champ! It took less than 10 minutes to get unboxed, assembled and spinning. Well thought out and the build is high quality. This is a must have for casting. It'll pay for itself in resin cost savings and no more problems with bubbles and air pockets in your castings. Used Smooth Cast 65D and Smooth Cast 300 and both work well for rotocasting. Great communication and fast shipping!
- ★★★★★
Pro-tocast Rotocaster WORKS! I bought this for my son so he could cast his original clay design toys. He was up and running almost immediately. Be advised that you should research the process and have some knowledge of the casting process. It is an entry-level piece of equipment so it's perfect for learning to cast, but you must also learn to make molds from silicone from you your own clay sculptures before you use it. It needs very little tweaking right out of the box and you will need about 4 square feet of table space to support it.

I'm new to casting and I've only used this a few times so far, but I'm very happy with it. It needed a little tightening up in spots but NBD. Also shipped and recieved waaaay ahead of schedule, so that was awesome.

Common questions
- What is a Pro-Tocast rotocaster?
- A hand-built machine that rotates your mold in two axes so resin coats the inside evenly. You get hollow casts—props, toys, parts—without the layer lines you see on a 3D print.
- Is this the same machine Krimplewips sold?
- Yes—same Pro-Tocast™ line, same workshop. We now sell direct at pro-tocast.com. If you ordered from Krimplewips before, you are in the right place.
- What sizes do you make?
- 10″ HD manual; 12″ manual and motorized; 18″ manual and motorized; and 30″ manual. Each size is its own frame—not one design stretched to fit.
- Do you ship outside the United States?
- Yes. We build to order and ship worldwide. US orders include free shipping (Alaska and Hawaii too). Email us for an international quote before you buy.
- What is The Box?
- An adjustable molding box for silicone pours—use it with a rotocaster or on its own. Comes in 10″ and 14″ adjustable sizes.
- How do I order?
- Email us from this site, or shop Banly's on Etsy, eBay, and Amazon. Stripe checkout here is coming soon.
- What is rotational casting?
- You close a mold, add liquid resin (or similar), and rotate slowly so the material coats the walls. When it cures, you have a hollow part—handy for props, soft goods, and workshop castings.
- How does Pro-Tocast compare to professional rotocasters?
- Metal and industrial machines for prop studios are often listed from about $2,500 to $13,000 USD. Pro-Tocast frames are hand-built from wood in our workshop, start under $150, and ship worldwide—built for makers who need real rotational casting without factory-floor pricing.
