1. Product Overview
We deliver one-stop custom Injection Mold development and PP filter component injection molding service. This filter spare part is produced from PP raw material, matched with tailor-made Injection Mold made of S136 stainless mold steel hardened to HRC48-52. Designed as 1×4 multi-cavity setup, the Injection Mold outputs four filter components per molding cycle to boost production efficiency. Its cavity adopts hybrid surface craft: partial polished finish & partial textured surface to satisfy different appearance requirements on a single plastic part. All finished Injection Mold undergoes full dimensional inspection before delivery to guarantee steady long-term mass production of PP filter accessories.

3. Core Advantages
① Reliable S136 HRC48-52 Injection Mold
S136 stainless steel owns outstanding rustproof, anti-corrosion and wear-resistant features at HRC48-52 hardness, perfectly fit long-run continuous PP injection. Stable mold steel effectively avoids rust spot during production and extends the service life of the whole Injection Mold.
② Unique Mixed Polished & Textured Cavity
Combined surface treatment realizes dual effects on one filter part: polished area for smooth assembling matching surface, textured area for anti-slip outer appearance. No secondary post-processing needed after molding, greatly save subsequent processing cost.
③ 1×4 Multi-cavity Cost-saving Design
Four filter components finished in one single shot, shorten molding cycle and lower unit cost, ideal for medium and large bulk orders of filter spare parts.
④ Excellent PP Molding Performance
PP material features high chemical resistance, lightweight and good rigidity, making finished filter components durable for liquid and air filtration equipment assembly.
⑤ Full Customization Available
We customize whole set Injection Mold strictly based on clients’ 2D/3D drawings or physical samples; adjustable part dimension, texture area proportion and cavity layout as personalized project needs.

FAQ
Q1: What’s the service life of this S136 Injection Mold?
A: With regular daily maintenance, the S136 HRC48-52 Injection Mold can stably achieve over 550,000 shots for PP filter component production.
Q2: Can you revise texture area range on existing Injection Mold?
A: Yes, our mold workshop can modify etch texture scope or polish area according to updated customer design.
Q3: Are pre-production samples available before bulk molding?
A: Definitely, we provide trial samples after mold completion for your dimension and appearance confirmation.
Q4: Can this Injection Mold switch to HDPE/ABS material?
A: After injection parameter adjustment and gate fine tuning, the same Injection Mold supports HDPE or ABS molding after our technical assessment.
