Injection Mold Construction
Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity.
Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured. The two plate mold requires a single day in light, while the three plate mold requires two days. Mold construction depends on the shape of the component, which determines the parting line selection, runner and gate selection and component ejection system selection. The mold base size depends on component size and number of cavities to be planned per mold.
Design Considerations
Draft: Required in both the core and cavity for easy ejection of the finished component
Shrinkage allowance: Depends on shrinkage property of material core and cavity size
Cooling circuit: In order to reduce the cycle time, water circulates through holes drilled in both the core and cavity plates.
Ejection gap: The gap between the ejector plate face and core back plate face should hold dimension within the core. It must allow component to be fully removed from the mold.
Air vents: Removes gases entrapped between core and cavity (usually less than 0.02 mm gap), because excessive gaps can result in flash defects.
Mold polishing: The core, cavity, runner and sprue should have good surface finish and should be polished along material flow direction.
Mold filling: The gate should be placed such that the component is filled from the thicker section to thinner section.
How to pack the mould
1.Check mould component
2.Cleaning mould cavity/core and spread slushing oil on the mould
3.Cleaning mould surface and spread slushing oil on the mould surface
4.Put into the wooden case
5.Transport by sea
FAQ
Q1. When can I get the price?
A: We usually quote within 24 hours after we get your inquiry. If you are very urgent, please call us or tell us in your email so that we will regard your inquiry priority.
Q2. How long is the lead-time for mold?
A: It all depends on the mold's size and complexity. Normally, the lead time is 25-35days.
If the molds are very simple and not big size, we can work out within 15 days.
Q3. I have no 3D drawing, how should I start the new project?
A: You can supply us a sample, we will help to finish the 3D drawing design.
Q4. Before shipment, how to make sure the products quality?
A: If you don't come to our factory and also don't have the third party for inspection, we will be as your inspection worker. We will supply you a video for production process detail include process report, products size ,structure and surface detail, packing detail and so on.
Q5.Can you do post production?
A: Some customers in addition to plastic injection require post processing, assembly of their products and packaging.
We have done this numerous times and have the facility and staff ready for these processes. You are welcome to inquire about post production if you need it. Or send us a quote request for any part you need. We will be happy to assist you with the quote or any technical, packaging, post processing or shipping inquiry.
