The cost of scrap, resource drain, wasted time, and maintenance activities would outweigh the cost of tooling savings, so carefully evaluate how cost savings will affect overall performance.
Fremont, CA: When buying an injection mold, paying attention to detail during the process is crucial for long-term success and stress-free production. Any mold design considerations should be made right at the outset of the product development process. Others get started as soon as the tool order is set. In this step, the project manager's main aim is to keep the customer satisfied while avoiding manufacturing issues.
Here are six tips to remember when purchasing an injection mold:
Mold design review
The features of mold filling, cooling, and ejection should be prioritized. The majority of the decisions should be justified by simulation data and recorded previous experience. When it comes to ejection, consider why the component will stay on the tool's ejection side throughout each cycle and whether it can be extracted without any damage.
Standardize mold features
Ensure that you provide the mold maker with a clamping slot, lift bar, and connection size specifications. You must also specify your utility preferences, such as air, water, oil, and electricity, among others. Otherwise, when it moves or is transferred to other devices, the mold can need replumbing.
Suitable risk management, effective communication, and realistic timelines
Anticipating and budgeting for unforeseen challenges during the planning phases would help the project remain on track and under budget. For instance, after the initial mold sampling, preparing and communicating for a potential mold re-cut to get plastic features into the required tolerance range.
Report with the shop floor and quality groups
Now is the time to make sure your team has everything they need to hang the mold and weigh the parts correctly. The ports on water manifolds, the existence of controls for hot runners and coolant, heater cables and plugs, fittings, hoses, bolts, lifting belts, and other things should all be tested.
Consider cost savings on tooling
No amount of cost savings is worth it if it jeopardizes the mold's ability to be maintained, has the potential to impact part quality, or makes start-up and everyday output more difficult. The cost of scrap, resource drain, wasted time, and maintenance activities would outweigh the cost of tooling savings, so carefully evaluate how cost savings will affect overall performance.
Part design for long-term molding success
You don't want to quickly authorize a plastic component design only to discover later that it contains features that make injection molding difficult. True concept ingenuity comes from minds who can come up with appealing ideas while taking into account the constraints of the manufacturing process. When the component designer, mold creator, and injection molder collaborate, the best results are achieved.
