Part 1
In this video, we go through the process of re-creating a rare brake tail-light lens for a 1958 BMW Isetta. We go through setting up a properly made 2-part silicone mold with vents and a fill port, as well as many tips and tricks along the way. We will finally cast BJB's WC-783 Clear Polyurethane Resin in to produce a beautiful tail light lens that looks as good as the original!
Watch Part 2: • Make Auto Rubber Trim ...
Shop our selection of silicones or speak with our technical staff to help you pick the right one. We also have a huge selection of castable polyurethanes for making parts in the mold; from soft, flexible gels, tough rubber, on up to rigid plastics!

    @randallbourque1321@randallbourque13216 жыл бұрын
    • Hi Randall, yes you can certainly recreate a lens using 3D Printing technology. The key to success is your painted finish over the 3D Printed part. It must be a very high gloss, Class A finish or you will not have the clarity of an original as shown in the video. This means painting the pattern with a good quality, automotive type clear coat; i.e. no rattle cans. You want to put the labor and polishing effort in the pattern instead of polishing each piece out of the mold. As the mold wears down over time, you may need to hand polish the cast lenses to bring the gloss level up but at a certain point you'll have diminishing returns and it may be time to make a new mold.

  • Love your video, I am new to this mold making. Question, I have a glass lens similar to your lens for Rail road lamps, i did the bottom mold but now having trouble getting the acrylic vent rods to stick to the glass using a CA glue. My first rod stuck no problem but the rest are not. I used different CA glues as well and same issue. If i accidentally got mold release on the glass before trying the glue, do you think that would cause the problem? Is there something i can use to clean the glass? I also notice on your video (Perhaps an edit splice?) right before you were going to glue the rods on your lens for the 2nd mold half the accelerator bottle was taken away then put back. Was it used for any part of the rods for the CA glue?

    @brucemiessner735@brucemiessner735 Жыл бұрын
    • Any mold release on the surface will cause issues bonding the vents. Use a Q-tip with some rubbing alcohol to clean the area to get a better bond. We pre-sprayed the area with accelerator to help the vent bond quicker which is why you see it picked up and then set down again. 4:26

  • I've been watching other company videos and I do like this one best, quick, to the point. Curious about the pressure casting though....that face mask was a failure with the defects. Why is that? I would think with vacuum on the liquid prior to pouring, and then pressure when casting you would have no bubbles. Is it possible that the mold was sealed too well and too low of pressure was used? Reason I say that is because the fluid was not able to pass into some other area of relief. I've seen one guy cut little bladder "fishers" to allow the pressurized liquid to fill the little bladders, contain the bubbles, and allow the liquid to re-enter to fill voids.

    @alwcurlz@alwcurlz4 жыл бұрын
    • The face casting was pressure only (no vacuum degas of the urethane prior to pouring). Some sources recommend pressure casting only and that is not something we would recommend for clear materials as you can see in the face casting. A combo of vacuum and pressure is the best way to ensure quality clear parts in a highly detailed, closed mold like this lens.

    • Typically the mark from CA gluing the acrylic vent onto the pattern is minimal and can be scraped or sanded off if needed. Usually this spot is in an area that is not a cosmetic surface (hidden behind the part) so it doesn't cause an issue. Marks from vents on the part is the same with injection molded parts and dealt with the same way. If it needs to be a clean surface, then the pointed vent makes a very small mark and is much easier to deal with.

  • Would it be beneficial in any way to have some kind of vibrating jig to mount the mold on when the resin is curing. Would it remove air bubbles from the resin or create them?

    @KHFilms@KHFilms5 жыл бұрын
    • Generally speaking, it's not a very practical solution because vibration typically removes air bubbles best with materials that have a high filler content (think concrete or plaster). These urethane casting resins are un-filled and the surface tension of the material does not easily let go of air bubbles. So, that's why we use vacuum chambers to degas the material before it goes in, as well as proper venting to channel the air and material through the mold, and then we'll often use a pressure tank to deal with any incidental trapped air in the mold geometry. In other words, Vibrating Tables are more often used on large open top molds where the casting material has a high filler content and the bubbles can simply rise to the top vs trying to navigate to a vent hole.

    • The lenses are very strong and tough. The most important thing to do is follow our technical data sheet to achieve the best performance in a harsh environment like automotive parts require. Heat resistance is the biggest hurdle for plastic parts on exterior car parts and it is very important to ensure a proper elevated temperature post cure is done on any cast urethane part. Clarity with these materials is unmatched when compared to other castable resin systems and they also resist yellowing due to UV light thanks to our formulation. It is important to choose the correct formula to ensure it has our added UV stabilizers for outdoor use. It's best to email our technical department to ensure you have all the info needed and you can ask specific questions about your application: info@bjbenterprises.com

    • Make one mould of the entire lens.. then, for ex, if the lens has 3 different pigments.. you'll create 3 copies of the original lens. Than, cut the replicas to each speciffic color, and create an final mould for each one. Cast them all with their respective colors, and later on the finishing process, glue them together with an appropriate glue or resin. Not as easy, but works flawless!

    @triptheroad@triptheroad5 жыл бұрын
    • Typically this requires you to make a custom block that supports and follows the curve under the part. You can make this with a large block of clay to fill in the gap below as it sits on a flat surface, or you can make it using thin, flexible sheets of plastic, metal, or wood. You would press the flexible sheet up against the pattern and support it from behind with a scaffolding type structure, similar to building a concrete bridge. Once you have a curved parting board, you can build the mold walls from there.

    • We have many customers over the years making lens parts for classic Lincolns, Mercury, Plymouth, Ford, Chevy cars and more. These are small companies reproducing parts that are not made anymore, not just hobbyists. Typically they are used for tail lights, turn signal lenses, interior domes, and such. We don't recommend it for headlights due to the intense heat generated. The UV resistance is very good. Aliphatic polyurethane is one of the most UV and color stable resins available for making cast parts (in comparison to epoxy and polyester resins for example). This material is also used in theme park applications where parts are mounted outdoors. The key things to be successful using this material: make sure you have a good vacuum degassing pump/chamber, a pressure tank, and lastly a way to post-cure the parts with heat so you ensure the best heat resistance in the parts.

    @Ruweshed@Ruweshed4 жыл бұрын
    • RASHED ALQALLAF vacuum does not heat the material, it is decreasing air pressure on the liquid to the point bubbles and gasses expand and escape. You need a very strong vacuum pump that can pull up to 28-29 inches of mercury (1 bar) to do this effectively.

    • It's a Bell Jar set up commonly found in labs and scientific set ups. It makes viewing the vacuum process a little easier than typical vacuum chambers while doing the same job. The key in any vacuum degassing set up is the pump quality. Higher CFM and lower micron ratings are the goal.

    • As you get past 12-15 parts, you'll usually see some dullness start to show in the parts. You can hand polish these back to a nice shine if need be. At about 20-30 parts it typically starts to really show in the parts and it's best to make a new mold.

    • Yes, vacuum casting is a common method in the world of silicone mold making and casting but typically requires specialized equipment. Is there a specific reason you need to cure under vacuum? Most people will process similar to the video and use a pressure tank to eliminate any accidental trapped air bubbles, but for certain mold configurations (like an open top mold) you can use vacuum to help pull material into fine detail. We would need more info to give the proper advice.

    • @@bjbenterprises I could imagine for a tail light lens with red and clear you could make a mold of the whole thing and one of just one of the colored sections. Let's say red. The pour the red mold and let it set up, then move the piece to the mold with the clear and fill and set. I'd imagine it'd need a small overlap of the two pieces for them to bond. I may be oversimplifying it. I'd love to hear your thoughts. If you mold one shape and put it into a larger mold will the two layers bond? Would it be better to mold two separate pieces and bond them together another way.

  • Hi there! First of all, thank you because it's been made so clear. But, I have a petition, if you don't mind. The piece casted in this video is "relatively easy" to do. I mean, is completely straight in one side. But, for example, for the lens showed right in time 7:09, I'm wondering how you can do that. (as you can see, it's not straight in one side, but curved). I'm not suggesting you have to do another video to show that (but it's up to you ;) ), but a little explanation, or maybe just a picture with your cast solution, would be great. Thanks again! (I promise to show you what I'll make, in case you're curious. I have a spanish "SEAT 600" and a BMW k75 motorbike which I have to deal with...)

    • It might take creating two different molds and placing one "half" piece into the second mold and cast the remaining color. You might also create a silicone "block" that temporarily fills the space in the mold while you cast the first color, remove the silicone, and cast the second color. It's very tricky to do two color castings or overmolds.

    • There are some small shops that can do work like this. Typically, the large, upfront cost is making the molds. If you are only looking for one set of parts, that can be expensive. Doing this DIY if you are familiar with mold making and casting is not too bad. Many times people try to make several castings from a mold and sell those to offset costs.

    • The fit was very tight to the splitter board and using thin CA glue creates no appreciable glue line (raising the part up). In hindsight, it would have been good to show using a paste wax around that edge to create a very small wax seal since many parts wouldn't fit this nicely. Another method to lightly fasten a flat lens like this to the splitter would be to use basic white glue around the whole edge. This would create a nice seal and allow easy removal from the splitter when needed. Nice catch and thanks for the comment. Others will learn from discussions like this!
