Guide to All-Electric Injection Molding Machine for Precision Plastic Parts: 90T-200T TEII Series Fi

2025/11/28 By le zhan

Precision Plastic Parts 1-1

Precision plastic parts, such as medical components, automotive sensors, or electronic housings, require extremely high consistency. Even a deviation of 0.01 mm can render a part unusable. Hydraulic injection molding machines, due to their fluid-driven motion, struggle with pressure fluctuations, leading to uneven clamping and slow response times, which in turn cause injection instability. All-electric injection molding machine that uses servo motors to perform all functions, eliminating these problems and achieving precise control.

Topstar’s TEII series of electric injection molding machines goes a step further. Based on a dual platform (TE II all-electric and h-TE II hybrid), this series balances extremely high precision with flexible efficiency. Designed specifically to address the pain points of precision parts manufacturers, it offers stable mold protection, consistent clamping, and adaptability to a wide range of materials.

TEII Series All-Electric Injection Molding Machine: All-Electric Precision, Hybrid Flexibility

The TEII series solves this problem with two interchangeable platforms—TE II (all-electric) and h-TE II (hybrid)—so you pay only for the features you need for your production.

The TE II all-electric platform is suitable for operations requiring extremely high precision: medical device parts, microelectronic products, or parts with extremely tight tolerances (±0.02mm). Each part—clamping, injection, screw rotation—is driven by a servo motor, eliminating the “backlash” of hydraulic oil and achieving repeatability accuracy of ±0.1mm.

The h-TE II hybrid platform combines electric precision with hydraulic power, making it suitable for high-torque applications (e.g., thick-walled automotive sensors in the 200T model). Its clamping axis uses a servo-hydraulic system for a robust and stable lock, while injection and ejection remain electric to ensure accuracy. This reduces energy consumption by 40% compared to a fully hydraulic machine. These platforms are unique in that they share core components: the same high-rigidity mold design, modular injection unit, and control system. This means that if your production direction changes, you can upgrade from the TE II to the h-TE II with just a simple servo-hydraulic kit.

High-rigidity clamping: stability, protecting the mold and parts

For precision parts, clamping stability is crucial. Mold wobble can cause part deformation, mold cavity wear, and increased scrap rates. These all-electric injection molding machines effectively solve this problem with their clamping units, which are constructed from high-rigidity steel mold plates. Under full load, the mold plate deforms by less than 0.02mm.

Here is its practical application: Traditional electric injection molding machines use thin mold plates, which can deform by up to 0.05mm during clamping. For a 100mm wide part, this deformation can create a 0.03mm gap between the two halves of the mold—enough to cause flash or uneven wall thickness. The TEII’s 12mm-thick stress-relieving steel mold plate completely solves this problem: We tested a 150T TE II with a dual-cavity medical mold, and the cavity pressure sensors recorded no uneven stress over 5000 cycles. Mold protection is another key feature. The TEII’s servo-driven clamping device uses force feedback sensors to detect obstacles within 0.01 seconds and stops movement before damage occurs.

Linear Guides: Lighter Movement, Faster Cycle Speeds

Precision does not mean slower speed. The TEII series all-electric injection molding machines offer an optional linear guide system for the clamping unit. Linear guides reduce friction by 60%, allowing the clamping platen to move smoothly and avoiding “stick-slip.” This can reduce cycle time for small, precision parts by 5% to 10%. A microelectronics manufacturer used a 90T TE II electric injection molding machine equipped with linear guides to produce two mm-diameter connector pins; its processing cycle time was reduced from 8.2 seconds to 7.5 seconds, allowing an additional 1200 parts per shift.

Linear guides also improve the durability of the injection molding machine. Sliding guides wear down over time, requiring monthly lubrication and annual replacement. TEII’s linear guides, made of hardened steel and sealed bearings, offer a service life up to 5 times longer, a particularly valuable solution for high-volume precision injection molding. For example, a 200T h-TE II machine tool equipped with linear guides, operating 24/7 to produce automotive sensors, can produce over 3,000 more parts per week compared to the same machine tool equipped with sliding guides. Moreover, because linear guides maintain alignment better, scrap rates remain low even at high speeds.

Modular Injection Molding Unit: Adaptable to Various Precision Machining Needs

The modular injection molding unit of the TEII series all-electric injection molding machines can adapt to a wide range of materials—from rigid PEEK for medical devices to flexible TPE for electronic seals—without requiring extensive reassembly.

At the heart of this unit is a quick-change screw and barrel system. A 25mm screw can be replaced with a 30mm screw in just 20 minutes, making it suitable for various high-volume processing, or a standard screw can be replaced with a barrier screw. A medical device manufacturer uses this system to easily switch between PEEK surgical instrument handles and PP syringe barrels on the same 120T TE II injection molding machine, saving 80 production hours of reassembly time per month.

The injection molding unit is also equipped with a servo-driven screw rotation device, enabling 1000-level speed control. This is crucial for materials such as glass fiber reinforced nylon, which require gentle mixing to avoid fiber breakage. The TEII’s precise speed control reduces fiber breakage rates by 70%, surpassing hydraulic injection molding machines and increasing part strength by 15%.

TEII Series All-Electric Injection Molding Machine: Case Study

An aerospace supplier that manufactures 10mm-diameter sensor housings for aircraft engines had extremely stringent requirements: tolerances of ±0.015mm, surface-defect-free production, and 24/7 operation. Their existing hydraulic injection molding machine could not meet these demands, resulting in a scrap rate of up to 9% and frequent missed delivery deadlines.

Topstar recommended the 150-ton TE II all-electric injection molding machine, equipped with linear guides and a barrier screw. Here are the results after 60 days:

  • Scrap rate reduced from 9% to 0.8%
  • Cycle time reduced from 11 seconds to 9.5 seconds, increasing output by 16%.
  • Operator training time reduced by 50%, allowing them to add two new operators without impacting production.
  • Mold wear reduced by 40%.

TEII Series Enables Precision Plastic Product Manufacturing

Precision plastic parts manufacturing is a balancing act: you need tight tolerances, fast production cycles, and extremely low scrap rates—while also protecting expensive molds and keeping operators highly efficient. The Topstar TEII series all-electric injection molding machines achieve this balance perfectly with their dual-platform design, high-rigidity clamping, modular injection units, and user-friendly interface. Compared to hydraulic injection molding machines, TEII users have seen an average 65% reduction in scrap rate, a 12% reduction in production cycle time, and a 40% reduction in energy costs.
