Reels are the core carriers for carrier tape packaging, and their dimensional accuracy and structural stability directly affect the efficiency of SMT mounting. Traditional injection molding machines have problems such as slow molding speed, poor dimensional control and unstable mold clamping force, which easily lead to reel dimensional deviation (exceeding ±0.05mm), surface burrs and other defects, affecting the matching with carrier tape and贴装 efficiency.
Xiamen Hatro Electronics Co., Ltd. launched a high-speed precision injection molding machine specially designed for EIA-481 standard reel production. The equipment adopts full servo drive system, with response speed increased by 30% compared with traditional hydraulic injection molding machines, and molding cycle shortened to 8-12 seconds per piece, which greatly improves production efficiency. The precision mold clamping force is controlled at 50-200 tons, with a control accuracy of ±0.1 tons, ensuring stable mold closing and avoiding flash and deformation of reels.
The machine is equipped with a high-precision positioning system, which controls the dimensional tolerance of reels within ±0.03mm, fully meeting the requirements of EIA-481 international standards. The integrated intelligent control system can realize real-time monitoring of molding temperature, pressure and speed, and automatically adjust parameters to ensure stable product quality. It is compatible with high-impact PS, PC and other materials, and can produce 7×8, 13-inch, 15-inch and other full-series EIA-481 standard reels.
At present, the injection molding machine has been used in Hatro’s own reel production line, and the reel qualification rate has reached 99.8%. At the same time, it has been sold to more than 20 domestic reel manufacturers, helping customers improve production efficiency by 40% and reduce defect rate by 80%. With the continuous growth of reel demand in the global semiconductor market, the equipment will further promote the upgrading of the reel production industry.
