Aria’s Mold Making Process
Create a Drawing
The first step is obtaining or creating the design for the part to be molded, including all necessary dimensions, features, and specifications.
DFM
Design for Manufacturability (DFM) optimizes the part or product design to enhance its manufacturability in mold making.
Material Selection
The suitable mold material is selected, such as tool steel, aluminum, or other materials based on the specific application.
Production Mold
The mold cavities and cores are machined or formed using CNC machining or other techniques based on design specifications.
Surface Treatment
The mold surfaces that come into contact with the molten material are treated to improve release and reduce friction.
Mold Assembly
All mold components, including cavity, core, inserts, and cooling channels, are assembled into the mold base.
Sample Validation
After assembly, the mold undergoes testing and validation to ensure functionality and dimensional accuracy.
For mass production
Continuous monitoring of the mold’s performance is done during production to ensure consistent part quality.

Description
Wall thickness
Recommended cooling time in seconds is 2 x d² (d = wall thickness d).
A plastic part with a 2 mm wall thickness requires approximately eight seconds to cool. At 3 mm, the cooling time is 18 seconds.
Thin walls make the injection molding process easier. Thin parts cool quickly while saving the material. Faster cycle times multiply hourly output while reducing production costs. Wall thickness is affected by the material used. The recommended wall thickness for injection-molded parts is between 2 mm and 4 mm. When injection molded parts have thin walls, they can be up to 0.5 mm. thin.
Ribs
Make certain that rib thickness is below 60 percent of the nominal thickness. Keep rib height under three times the wall thickness. Maintain a draft angle of 0.25°. Ensure that alignment is perpendicular to the axis. Maintain rounded corners at the attachment points.
These thin, wall-like structures give injection molded parts rigidity and strength. Because they’re thinner than primary walls, ribs can support injection-molded parts as well as bosses by running perpendicular to these structures. The components can replace thick wall sections to prevent sink marks, warp, and voids. Ribs can also provide a part with flexural rigidity due to an increased moment of inertia.
Radius
We recommend an inner radius that’s equal to the wall thickness at least.
Rounded corners reduce internal stress concentration to prevent breakage. Sharp corners intensify internal stress concentration and can cause plastic parts to fail. Increased demand will also occur during the production process.
Draft
We recommend an inner radius that’s equal to the wall thickness at least.
When towing or ejection lines occur, plastic parts can be a challenge to eject.
Undercust
We recommend omitting undercuts from the design. If they must be used, a moving slide unit must be installed in the tool. That raises costs significantly.
Grooves, notches, and other relief-like structures can interfere with the demolding process of an injection molding tool. If these structures occur in the injection molded part, they can cause unacceptably high levels of strain. The degree of strain depends on the size and position of the undercuts during demolding. Parts with large undercuts cannot be removed from a simple injection mold.
Shrinkage
The following formula is used to calculate processing shrinkage:
- S = (D – d) / D (× 100%)
- D = dimensions of the cavity
- d = dimensions of the injection molded part
This is inevitable during the injection molding process. Following injection, cooling reduces size and volume. The degree of shrinkage differs according to the materials used.
Preparation For Mold Making
Conduct a Feasibility Analysis
We complete a feasibility analysis based on a Design for Manufacturing (DFM) report. We then share our feedback with the client and offer useful suggestions to prevent errors during the production phase. Identifying problems in advance gives us the information we need to correct potential glitches straightaway. That reduces total costs and allows us to craft products of exceptional quality.
Complete a MoldFlow Simulation
Using the latest MoldFlow software, we can determine the ideal position for a mold as well as the optimum temperature control before commencing the production of plastic parts. MoldFlow simulation is an essential component of the concept phase. It predicts the physical activity of plastic parts. By simulating the production phase before actual production, we can identify and prevent issues with weld lines, air pockets, and dents.
Execute a Filling Analysis
Using state-of-the-art computer-aided design (CAD) software and computer-aided engineering (CAE) technology, we can accurately simulate an injection molded part before installing it and predict the fill status. Uneven mold fillings can change the shape of the finished part. An early MoldFlow analysis keeps that from happening.

Cost Optimiziation
The total cost of production can be reduced through efficiencies in the process. This includes adaptations designed by a professional team of engineers. They create processes for reducing the cycle time, increasing the productive capacity, and trimming costs out of the process. Procurement and maintenance are also carefully scrutinized to avoid redundancies.
Parts Design
An outstanding parts design reduces complexity and eliminates unnecessary costs.
Precision tolerance
Injection-molded precision parts that require a high gloss finish also require extra manual grinding following production. That increases a mold’s manufacturing and maintenance costs.
Production volume
Mass production of plastic parts requires highly sophisticated injection mold tooling. Increasing the number of cavities will increase production capacity. However, tools with multiple cavities have higher manufacturing costs.
Size of parts
The larger a part, the more material it requires. The more material, the higher the cost.
Length of cycle
To accomplish a short cycle with plastic injection molding, the tool must quickly and uniformly cool the cavities. Precision molds speed up the cycle, but they also increase the cost.
Cooling time
The larger a part, the more material it requires. The more material, the higher the cost.
Size of parts
An injection mold’s uniformity and cooling time determine the efficiency of the process. The shortest cycles are achieved with uniform cooling throughout the cavity. Cooling time differences can profoundly affect the mold manufacturing process.
Mold Material
Plastic injected parts that are volatile or corrosive can generate higher temperatures and additional pressure. The mold steel will require exceptional material properties to withstand the burden.
Gate location
Gate location has a direct effect on molded parts. If the gate can’t be positioned on the mold side, the injection molding tool will need additional construction. Generous use of the hot runner system can up the tooling price. Nevertheless, it will lower the unit price of the molded part and the complexity of the tool.
