Use full tips. Since the little knobs on these pastel ribbed containers are delicate, especially during demoulding, here are some practical tips you can share with your clients to help prevent breakage:
Demoulding Tips to Protect Knobs:
- Let it Cure Fully
Always allow the resin or material to cure completely. Premature demoulding increases the risk of snapping off fine details like knobs. - Use Mold Release Spray
A light coat of mold release before pouring helps the piece slide out more easily, reducing stress on fragile areas. - Flex the Mold Gently
Loosen the edges by gently flexing the mold all around before attempting to remove the piece. This helps release suction and eases the process. - Push from the Base, Not the Top
When removing the lid, push from the underside or base of the knob rather than pulling on the knob itself. - Warm Water Bath (Optional)
If the mold is stubborn, a quick dip in warm (not hot) water can soften the silicone slightly and make demoulding smoother. - Avoid Rushing
Encourage a slow, patient approach. Rushing is the number one cause of broken knobs!
Note that, packaging and transportation can indeed cause some moulds to deform. Soaking the mould in hot water and then using rice to help reshape it is a practical solution.
Here are a few additional tips for mould remediation:-
1. Freezing Method: If the mould is made of silicone, you can try placing it in the freezer for a few hours. This can sometimes help the mould return to its original shape.
2. Supportive Fillers: Besides rice, you can use other fillers like sand or small beads to help reshape the mould. Make sure the filler is dry and can conform to the mould’s shape.
3. Gradual Heating: For more delicate moulds, gradually heating them with a hairdryer can help. Be careful not to overheat, as this can cause further deformation.
4. Storage Tips: To prevent future deformation, store your moulds flat and avoid stacking heavy items on top of them. If possible, keep them in a cool, dry place.
5. Use of Weights: After soaking in hot water, place the mould on a flat surface and use weights to hold it down in its correct shape until it cools and hardens.
