1*2 Cavity PA6+30GF Material Hot Runner 2344 HRC48-52 Mold Steel SPI-B2 Texture Plastic Housing Part Mould

Product Overview

Key Features

✅ 1×2 Cavity Balanced Design for High Efficiency

• The 1×2 cavity layout produces two identical housing parts per cycle, doubling output while maintaining perfectly balanced melt flow and uniform pressure distribution across both cavities.

• The symmetrical runner system ensures identical fill conditions for each part, eliminating quality variation and minimizing cycle time for cost-effective medium-to-high volume production.

• Reinforced mould plates and precision guide pillars prevent deflection under the high injection pressures required for glass-filled materials, preserving critical dimensional tolerances on mounting bosses and snap-fit features.

✅ Hot Runner System Optimized for PA6+30GF

• The integrated hot runner system eliminates cold runners, drastically reducing material waste and cycle time, which is especially critical for high-cost glass-filled resins.

• Heated nozzles maintain uniform melt temperature, preventing premature solidification and ensuring complete, uniform filling of the housing’s complex geometry, including deep ribs and thick bosses.

• The system prevents gate freeze-off and drooling, ensuring clean, consistent gate quality and reducing post-processing.

✅ 2344 HRC48-52 Mould Steel Construction

• Built from high-grade 2344 (1.2344) hot-work tool steel, hardened and tempered to HRC48-52, this mould offers exceptional wear resistance and toughness.

• The high hardness is critical for withstanding the abrasive nature of glass-filled PA6+30GF, preventing premature wear of the cavity surface and maintaining sharp, clean part edges over long production runs.

• The steel’s excellent thermal stability and resistance to thermal fatigue ensure consistent mould performance even under the high processing temperatures required for glass-filled nylon, resulting in a long service life of ≥1,000,000 cycles.

✅ SPI-B2 Fine Matte Texture Finish

• The mould cavities are precision-finished to SPI-B2 standard (fine matte texture, Ra 1.6–3.2 μm).

• This texture is ideal for PA6+30GF parts, as it helps to hide minor surface imperfections caused by glass fibers, improves mold release, and provides a uniform, professional appearance.

• The fine matte finish also reduces friction between the part and the mould, minimizing the risk of scratches or sticking during ejection.

✅ PA6+30GF Specialized Cooling & Venting

• The mould features an optimized cooling channel layout, with cooling lines positioned close to the housing’s thick sections and bosses to ensure fast, uniform cooling. This controls the material’s high crystallinity and prevents warpage or sink marks.

• Precision venting at the part’s edges, rib intersections, and deep cavities effectively discharges trapped air, eliminating burn marks or incomplete filling caused by the material’s high viscosity.

FAQ

1. Q: Why use PA6+30GF for this housing part?

   A: The 30% glass fiber reinforcement significantly increases the material’s rigidity, strength, and dimensional stability, making it ideal for structural housings that require load-bearing capacity and resistance to heat and deformation.
2. Q: Why is 2344 steel chosen for this mould?

   A: The high hardness (HRC48-52) of 2344 steel provides excellent wear resistance, which is essential for withstanding the abrasive glass fibers in PA6+30GF. This ensures the mould maintains its precision and surface quality over millions of cycles.
3. Q: What are the benefits of a hot runner system for PA6+30GF?

   A: It eliminates wasteful cold runners, which is crucial for expensive glass-filled materials. It also ensures consistent melt flow, prevents material degradation, and reduces cycle time.
4. Q: What does the SPI-B2 texture do for the housing?

   A: The fine matte finish hides minor surface blemishes from glass fibers, improves mold release, and gives the part a durable, non-glare appearance suitable for industrial and automotive applications.
