Injection Molding Process Selection: Which Molding Solution Is Best For Your Product?

Since there are various plastic injection molding processes, the most appropriate molding solution needs to be selected in order to increase product performance, control costs, and improve production efficiency. Bad decisions can lead to flaws, cost overruns, or lengthy production schedules.

1. Two-color injection molding:

If your product contains a combination of hard and soft material or multi-colored design (e.g., two-color buttons or soft rubber grips), two-color injection molding is the best. It is a single-piece molding process that eliminates post-assembly.

2. High-speed injection molding:

For manufacturing thin-walled structural parts (e.g., packaging and housings), high-speed injection molding provides high-volume production at very short cycle times with high speed.

3. Insert molding:

If your product contains metal inserts or electronic components inside, insert molding would be selected so that there is maximum interlock between the insert and plastic.

4. Micro injection molding:

For very small high-precision parts (e.g., medical catheter connectors and optical lenses), only micro injection molding technology can meet their extremely high dimension requirement.

When selecting a process, consider product geometry, material characteristics, volume of production, and cost. LS Precision's experienced staff of experts can provide in-depth analysis and solution verification to ensure your plastic injection molding process investment is the ideal solution for your product requirements.

There is no one process that will be perfect for all products. The key to successful production and the overall expense of plastic injection molding is the proper alignment of the product's requirements.

What Are The Key Factors Affecting Injection Molding Costs? How Can They Be Optimized?

Precise plastic injection molding cost management is vital to the success of large-scale production. Cost is not a stand-alone number; it is an integrated result affected by a variety of parameters like material, mold, complexity of design, and batch size. Information on these parameters and their optimization can significantly increase the product's competitiveness in the market.

1. Material selection:

Material selection is the cost structure element with high impact in plastic injection molding. The engineering plastics (e.g., PC and Nylon) are significantly more expensive than the general-purpose plastics (e.g., PP and ABS).

Optimization Suggestions: Since performance is guaranteed, choose cost-efficient material or negotiate with the suppliers on the amount of recycled material to use.

2. Mold complexity:

Mold complexity is a direct factor influencing initial investment. Multi-cavity precision mold with sliders and lifters will be expensive.

Optimization Suggestions: Simplify product design, eliminate unnecessary undercuts and complex structures, and use standard mold bases. This can significantly lower mold costs.

3. Production batch:

Production batch size has significant impact on unit cost. Large-volume production reduces the mold cost significantly, while trial production in small lots raises unit costs.

Optimization Recommendations: Plan production accordingly and perform design verification ahead of time through CAE simulations to remove additional cost of trial-and-error mold modification.

Plastic injection molding cost optimization is a process. Success lies in starting at the design source, together with experienced suppliers, and pursuing an integrated policy of materials selection, design minimization, and production scheduling to ensure quality while achieving optimum cost control.
