SMV

Product catalog summary

Overview: The document describes the SMV compact valve gate system designed for use with machines having a clamping force capacity of 15t to 50t. It is particularly suitable for super engineering plastic molding.

Key Features:

The system has a thin stationary side height of 120mm.
Equipped with a standard tip heater to optimize molding conditions, especially for filler-contained plastics.
An air drive system combined with a guiding mechanism minimizes wear and tear on the gate and pin.
Easy handling and maintenance are facilitated by the air drive system.

Technical Specifications:

Body heater operates at 32V (AC) and tip heater at 11V (AC).
The overall length of the body is limited to 45mm.
Gate sizes available are 0.8mm and 1.0mm.
Compatible with the S2000・AHC controller; other controllers are incompatible due to voltage mismatches.
Valve activation is air-driven at 0.5Mpa.

Design Example: A trial mold by Seiki is provided with part dimensions of 30mm x 40mm and wall thickness options of 0.5mm, 0.8mm, and 1.0mm. The molding machine used is a 15t NEX15.

Material Specifications: The document lists various resin grades with corresponding resin and mold temperatures, part weights, and end-use applications, such as automobile interiors. Examples include:

PA66 (G=30%) with a resin temperature of 290℃ and mold temperature of 80℃.
PA46 Stanyl (GF40%) with a resin temperature of 300℃ and mold temperature of 110℃.
LCP VECTRA with a resin temperature of 340℃ and mold temperature of 80℃.

Conclusion: The SMV system is a versatile and efficient solution for plastic molding applications, offering ease of use and maintenance, along with compatibility with specific controllers and materials.
