Mold Making And Resin Casting – How I Make Plastic Copies of My Toys

I super-glued a round piece of plastic to the model . This was used to suspend the fish in the cavity of the mold frame. It also forms a channel that allows the melted plastic to enter into the mold during the final injection step.Note: this mold frame had cutouts for sprues on all 4 sides, so I had to block the other three cutouts. But, I noticed that the epoxy mold frames on the www.techkits.comwebsite now only have a single sprue cutout, so this may no longer be necessary.

Basic Design Principles For Injection Molding

TolerancesWith our injection molding process, we can hold about ±0.003 in. machining accuracy. Shrink tolerance depends mainly on part design and resin choice. It varies from 0.002 in./in. for stable resins like ABS and polycarbonate to 0.025 in./in. for unstable resins like TPE.Wall ThicknessWall thickness is important because it can lead to defects such as sink and warp. It is best practice to maintain a uniform thickness throughout an injection-molded part. We recommend walls to be no less than 40 to 60 percent of adjacent wall thickness, and all should fit within recommended thickness ranges for the selected resin.

Core GeometryCore out parts to eliminate thick walls. You get the same functionality in a good molded part. Unnecessary thickness can alter part dimensions, reduce strength, and necessitate post-process machining.

DraftApplying draft to molded parts is critical to ensure parts do not warp during the cool down process and it helps the part easily eject from the mold. Applying 1 to 2 degrees works well in most scenarios. If there are vertical faces, we advise incorporating .5 degrees of draft.

Side ActionsA portion of the mold that is pushed into place as the mold closes, using a cam-actuated slide. Typically, side-actions are used to resolve an undercut, or sometimes to allow an undrafted outside wall. As the mold opens, the side action pulls away from the part, allowing the part to be ejected. Also called a cam.

Chlorine bleach is quite effective in cleaning all types of house siding, concrete, brick, and stone, but it is harmful to plants and lawns. Be sure to cover any vulnerable plants with heavy plastic sheeting.

Mix one cup of chlorine bleach to one gallon of water. The solution can be used with a garden sprayer, power washer, or for hand-scrubbing. Always wear safety glasses, gloves, protective clothing, and a respirator. The bleach solution will cause color-loss on any type of fabric.

Wet the moldy areas with plain water, then the bleach and water solution, and allow it to work for several minutes. If the mold lightens, move to another area. If stains remain, scrub the area and then reapply more bleach and water solution. Allow to air dry completely.

Rinse down nearby planted areas with plain water.

    Learn Resin Casting Techniques: Duplicating Plastic Parts

    The Principle Of Plastic Mold Blow Molding

    Resin casting lets you produce parts that would be otherwise impossible to make without a full CNC and injection molding set-up. It costs about as much as a 3d printer, 300 to 600 US dollars, to get a good set-up going. This is for raw material, resin, dye, pressure chamber, and an optional vacuum degassing set-up. A good resin casting set-up will let you produce parts which are stronger than injection molding, and with phenomenal accuracy, temperature resistance, and strength. I will be covering various techniques from the simple to advanced for using resin casting from a hackers perspective.

    Today I will be replicating a part exactly. I searched my house for a pending project. I wish I had a more exciting part to duplicate, like a broken hinge or plastic case that Id like in a different color, but I lost a button on my favorite coat. So Ill be making a matching set of buttons.

    Youll need a basic resin casting set-up. For the raw materials, I duplicated the suggestions from the Guerrilla Guide the standard handbook for fabricating things in your own workshop. So far this has worked out great. Ive also had a lot of fun casting urethane rubber for wheels and flexible parts, but thats for another chapter.

    Classification Of Injection Mold:

  • 2 plates mold: another name of the sprue gate mold, also known as the single parting line type plastic injection mold, its characteristic is the simple mold structure, but the sprue is a part of the injection molded part, and it needs to be manually removed later, and plates mold structure is widely used for various kinds of mold.
  • 3 plates mold: the pinpoint gate mold and the double parting line type injection mold. Its gate characteristic is pinpoint, and the gate cross-section is small. The injection molded part appearance is good, and because it does not need the manual removal of the gate later, it is advantageous for the automation production. But three plates mold structure is more complex, and the cost is higher. It is generally applicable to small and medium plastic parts. And plastic molding material is with good fluidity.

    Advantages And Disadvantages Of Nylon

    The advantages of nylon PAs include their toughness and high heat resistance. They also have high abrasion resistance, good fatigue resistance, and noise dampening properties. With its low coefficient of friction, injected molded nylon is suitable for high friction and wear applications.

    Although nylon does not offer inherent flame resistance and can burn quickly, flame retardant versions are available. Similarly, although nylon can be degraded by sunlight, a UV stabilizer can be added to improve performance. In addition, the material offers poor resistance to strong acids and bases.

    Injection molded POM combines excellent rigidity with thermal stability and a low coefficient of friction. It also has low water absorption and good chemical resistance. Two main types of POM plastics are available: homopolymers and copolymers. This gives engineers and designers a choice of acetal materials with different properties.

    In its pure form, POM has low impact strength and a very high rate of thermal expansion. Mold shrinkage is relatively high and acetals do not resist UV light. POM plastics that are homopolymers provide higher hardness and tensile strength. However, all POM plastics cannot be fire-rated to a standard such as UL 94.

    How To Clean Plush Toys In The Washer

    Colorfast, plain stuffed animals and fabric books are usually safe to clean in your washing machine. Sturdy plush toys can be washed and dried on the sanitizing cycles, if your machines have them, but many plush toys come with care labels, so its a good idea to check how the manufacturer recommends cleaning it, especially if the toy is new. Heres how to clean em in the washer:

    • First, put plush toys in a pillowcase to protect them and knot the top.
    • Select the gentle cycle, warm water, and a slow spin.
    • Dry the toy in your dryer on a low-heat setting. Or, if your dryer has a rack, take the toy out of the pillowcase and set it on the rack to dry without tumbling.
    • For a gentler approach, use a hair dryer on low heat and speed settings. When the teddy reaches the just-damp stage, switch to the hair dryers medium setting to fluff up the fur.

    Keep in mind: Never wash plush toys with built-in battery packs, noise makers or other metal parts, as the water may damage them. Make sure all decorations and buttons are securely attached, any rips and holes are repaired.

    Why Does Mold Grow On Plastic

    Many people believe that Mold is not able to grow on plastic or polymer materials. Mold generally canât break down plastic easily.

    However, plastic contains many additives, such as plasticizers, cellulose, lubricants, stabilizers, and colorants to help provide desired features, and these additives ARE very easy for mold to break down.

    Once mold becomes established by breaking down the easily digested ingredients, the acids they produce as by-products of growth break down the resin into a more useable food source.

    To learn more, read up on the ASTM G 21 test method that describes this process in greater detail.
