What are Some Common Problems in Low Cost Injection Molding?

Low cost injection molding is an injection molding solution that balances production efficiency and cost control, suitable for various scenarios such as small-batch trial production and regular mass production. However, low cost injection molding is limited by raw material, equipment, and process inputs. Common problems fall into the following categories:

1. Raw Material Issues: Excessive use of recycled materials and low-grade raw materials easily leads to defects such as material inclusions, loose fibers, and brittle products. Inadequate raw material drying can also cause silver streaks and bubbles, directly reducing the product's structural strength and appearance pass rate.

2. Process Debugging Issues: Blindly increasing the compression cycle speed easily leads to defects such as short shots, flash, and scorching. Inappropriate holding pressure settings can cause shrinkage, warpage, and excessive product dimensional deviations, failing to meet assembly requirements.

3. Mold and Equipment Issues: Insufficient precision in low-cost molds and rudimentary venting systems easily lead to problems such as weld lines and poor demolding. Unstable pressure in old equipment can cause large fluctuations in product batch quality, making it difficult to guarantee a high yield rate.

4. Long-term hidden problems: Low-cost production often omits raw material pretreatment and regular mold maintenance, which accelerates the wear and tear of equipment and molds. The hidden costs of subsequent rework and repair increase significantly, and the overall production efficiency decreases.
