From our experience very challenging to work with this mould.\n\nThe mould needs to have a proper adapter/connection method. We use a car jack to push the mould inlet onto the injection nozzle. \n\nSome lubrication is needed on the insert bit. If the product is left to cool for too long on the insert, it tends to shrink and get stuck on the insert. The best way to release is to use rubberized gloves and pull in the twisty/rotating manner. \n\nFollow-up: the injection point needs to be clipped off with pliers/ knife and a hole should be drilled at the end with a drill bit 6-8mm in diameter. It is easier to drill from the inside of the jump rope handle with a longer drill bit.\n\nTo finish the jump rope, we use 6mm rPET paracord type rope (recycled)." _deleted: false tags: - "injection" - "mould" votedUsefulBy: - "peninsulapreciousplastics" - "mattia" - "marcelaazoubel" slug: "jump-rope-handles-mould" fileLink: "" _contentModifiedTimestamp: "2023-10-29T16:31:58.871Z" comments: [] mentions: [] creatorCountry: "ee" user: _modified: "2024-01-23T16:20:01.540Z" moderation: "accepted" verified: false _id: "precious-plastic-estonia" _created: "2024-01-23T16:20:01.540Z" subType: "mix" location: lng: 24.729044437408447 lat: 59.438815706488 type: "workspace" _deleted: false geo: latitude: 59.438815706488 lookupSource: "coordinates" longitude: 24.729044437408447 localityLanguageRequested: "en" continent: "Europe" continentCode: "EU" countryName: "Estonia" countryCode: "EE" principalSubdivision: "Harjumaa" principalSubdivisionCode: "EE-37" city: "Tallinn" locality: "Pohja-Tallinn" postcode: "" plusCode: "9GF6CPQH+GJ" localityInfo: administrative: - name: "Estonia" description: "republic in North Europe" isoName: "Estonia" order: 4 adminLevel: 2 isoCode: "EE" wikidataId: "Q191" geonameId: 453733 - name: "Harjumaa" description: "county of Estonia" isoName: "Harjumaa" order: 6 adminLevel: 6 isoCode: "EE-37" wikidataId: "Q180200" geonameId: 592170 - name: "Tallinn" description: "capital and most populous city of Estonia" order: 7 adminLevel: 7 wikidataId: "Q1770" geonameId: 588409 - name: "Tallinn" description: "municipality of Estonia" isoName: "Tallinn" order: 8 adminLevel: 7 isoCode: "EE-784" wikidataId: "Q4450503" geonameId: 862995 - name: "Pohja-Tallinn" description: "district of Tallinn" order: 9 adminLevel: 9 wikidataId: "Q1632061" geonameId: 8435741 informative: - name: "Europe" description: "continent" isoName: "Europe" order: 1 isoCode: "EU" wikidataId: "Q46" geonameId: 6255148 - name: "North European Plain" description: "geomorphological region in Europe iceland" order: 2 wikidataId: "Q560549" - name: "Europe/Tallinn" description: "time zone" order: 3 - name: "Baltic states" description: "3 countries east of the Baltic Sea (Estonia, Latvia, Lithuania)" order: 5 wikidataId: "Q39731" data: urls: - name: "Facebook" url: "https://www.facebook.com/estpreciousplastic" - name: "Instagram" url: "https://www.instagram.com/estpreciousplastic/" - name: "Website" url: "https://plastic.makerspace.ee/" - name: "Email" url: "mailto:estpreciousplastic@gmail.com" - name: "sponsor the work" url: "https://www.patreon.com/one_army" description: "Precious Plastic Estonia is a local initiative that educates people about the problems related to plastic waste management, encourages community to become more active in solving these problems and recycles waste plastics into useful products." services: - welding: false assembling: false machining: false electronics: false molds: false title: "Precious Plastic Estonia" images: [] detail: services: [] urls: [] images: []
