SDIR400 Rubber Injection Molding Machine

Release Date:2026-08-27 10:39:04

SDIR400 Horizontal Rubber Injection Molding Machine

SDIR400 is a 400‑ton single‑shaft horizontal rubber injection molding machine from Xinduo Machinery. Built with robust construction and high operational stability, it features large injection volume, high precision and low maintenance cost, specially designed for mass production of medium‑to‑large‑size rubber products.

Features

  • Adopts brand‑new shuttle‑type non‑return structure with streamlined feed channel without dead corners, sensitive opening‑closing without jamming
  • Extended effective stroke of injection barrel, offering sufficient space for maintenance operation
  • Max. injection volume 5000CC, equipped with 210Mpa high‑pressure injection system for one‑piece molding of large‑size products
  • Exclusive thermal insulation design for transfer injection plate cylinder, isolating high‑temperature conduction from barrel to protect hydraulic components
  • Low‑profile compact horizontal frame, no special requirement for factory ceiling height, flexible installation and placement
  • Fitted with imported heat‑medium oil pump; temperature control accuracy reaches 200℃±3℃ for uniform heating and vulcanization
  • Screw and barrel made of 38CRMOALA alloy steel with nitriding hardening treatment, high hardness, wear‑resistant and corrosion‑resistant
  • 18.5KW industrial motor with variable‑frequency power system, soft start, low noise and low energy consumption
  • 700×700mm large worktable for wide mold compatibility
  • Over 20 years of industry technical accumulation from Xinduo Machinery with mature manufacturing process and complete after‑sales support

Advantages

  • Smooth feeding without jamming; longer service life of core components, lower breakdown rate and stable continuous production
  • Simple and time‑saving disassembly for maintenance, reducing downtime, improving equipment availability and cutting labor cost
  • Huge injection capacity for dense and uniform molding of thick‑wall & large‑volume products with excellent production output
  • Cylinder thermal insulation protection slows oil seal aging and hydraulic oil deterioration, greatly extending service life of hydraulic parts and reducing replacement cost
  • Low‑profile compact frame, installable in ordinary workshops without factory reconstruction, excellent site adaptability
  • Stable & uniform temperature control reduces molding defects such as short shot and color difference, effectively improving product yield rate
  • Wear‑resistant & high‑temperature‑resistant plasticizing components for long‑term continuous mass production; better stability than ordinary models
  • Variable‑frequency energy‑saving system with low starting current and low grid load; high universal spare parts and low maintenance threshold
  • Optimized through years of real‑world working‑condition iterations, well‑adapted to domestic production demands with low overall failure rate
  • 3‑year warranty for core castings; easy procurement of standard wearing parts, rapid professional after‑sales response to secure production‑line operation

Application Scope: Silicone Rubber Products

Suitable for mass production of medium‑to‑large‑size, thick‑wall silicone rubber products. Compatible with common silicone rubber compression‑injection products, meeting one‑piece mass‑production requirements for various silicone rubber workpieces.
