BM Plast with Chen Hsong’s TP-Smart
Client: BMPLAST
Location: Lima, Peru
Industry: Industrial & Consumer Packaging
Machine: TP-Smart 1700T (Two-Platen)
Deep cavity molding is one of the more unforgiving applications in plastics manufacturing. It requires a specific combination of machine mechanics: massive opening strokes to eject tall parts, yet rigid clamping to prevent flash. In Lima, Peru, industry veteran BMPLAST is tackling this challenge head-on. By deploying the Chen Hsong TP-Smart 1700T, they have successfully optimized the production of heavy-duty deep cavity buckets.

The Challenge: Depth vs. Footprint
Producing large industrial buckets presents a geometric problem. The mold needs a significant amount of daylight and opening stroke to clear the core. On traditional toggle machines, achieving this stroke often requires upsizing the machine tonnage significantly, which wastes energy and eats up valuable floor space.
Furthermore, deep draw parts are susceptible to specific defects. If the injection pressure isn’t perfectly balanced, you get warpage. If the clamp force isn’t uniform, you get flash. BMPLAST needed a solution that offered the physical space for large molds without the footprint penalty, while ensuring the precision required for uniform wall thickness.

The Solution: TP-Smart Two-Platen Technology
BMPLAST selected the TP-Smart 1700T because it is purpose-built for this exact scenario. As highlighted in the technical specifications, the TP-Smart series utilizes a Japanese-designed two-platen structure that offers the largest stroke and daylight in the smallest possible footprint.
1. Solving the Space Issue
The two-platen design eliminates the long tail of a toggle mechanism. This allowed BMPLAST to fit a 1700-ton machine into a tighter facility layout while still having ample room to accommodate the deep-draw molds required for their buckets.
2. Precision in Filling
To ensure the buckets remain durable and defect-free, the TP-Smart utilizes dual injection carriage cylinders. This setup provides perfect balance and the necessary pressure to push material through long flow paths consistent with deep cavity molds. The result is a bucket with uniform strength from the rim to the base.
3. Cycle Speed and Mold Protection
Efficiency matters. The TP-Smart features a patented lock-nut design and a Gen-4 Servosystem. This technology allows for high-pressure release speeds and fast clamping movements. Crucially, the system is designed to reduce impact. This protects BMPLAST’s expensive molds from wear and tear over high-volume production runs.
The Result: Operational Excellence
For BMPLAST, the installation of the TP-Smart 1700T has translated into stable, high-quality output. The machine’s “Non-Stop” fault-tolerant technology ensures that annual downtime remains exceptionally low, a critical factor for a company serving both daily packaging and industrial needs.
By leveraging the “Smart Control” platform, their operators can easily manage the complex parameters of deep cavity molding. The result is a production line that is not only faster but significantly more reliable.
