Plastic Toilet Brush Holder Mould

Product Parameter

Product Introduction

Plastic Toilet Brush Holder Mould is specifically designed for the efficient mass production of plastic bathroom brush cylinders, compatible with PP, ABS, and eco-friendly recycled base materials, suitable for 120-300-ton injection molding equipment, and covering the full range of products from basic single-slot models to multifunctional water-storage models. It adopts a modular architecture integrating embedded mold frames, multi-cavity molding units, and a precision injection system. Through the precise coordination of upper and lower inserts, it achieves integrated molding of the main body, hanging holes, and drainage structures, eliminating secondary processing. Customized distribution plates and multi-channel flow distribution structures ensure uniform melt filling, addressing shrinkage issues at the junctions of thin and thick walls. The entire process adheres to ISO 9001 standards, involving 12 precision procedures such as incoming material inspection, five-axis machining, WEDM, and vacuum heat treatment. Zeiss coordinate measuring machines perform comprehensive inspections to ensure cavity tolerances of ≤±0.005mm, matching the assembly precision of brush cylinders and brush heads. During the trial molding phase, core process data such as melt temperature, clamping force, and cooling parameters are provided to help customers quickly establish a stable mass production system. K-SHOW is a professional manufacturer and supplier of plastic molds. Welcome to consult.

Product Features

1. Optimized Structure, Leap in Molding Efficiency

Adopting a 2-4 cavity modular design, through the symmetrical layout of injection distribution parts and flow balance control, it realizes synchronous molding of multiple products, and the production efficiency is increased by 100%-300% compared with traditional single-cavity moulds. For the tooth-shaped limit structure and assembly buckle of the brush holder, an innovative design of precise matching structure between tooth-shaped molding protrusions and grooves is adopted, combined with the positioning mechanism of alignment clamping grooves and buckles, to avoid plastic part defects caused by cavity misalignment, and the molding qualification rate is stable above 99.5%. The built-in flip gate design of Plastic Toilet Brush Holder Mould can hide the injection marks in the side flanging holes of the brush holder, without affecting the appearance integrity of the product at all.

2. Precision Temperature Control, Stable Plastic Part Quality

The customized built-in cooling pipeline system extends close to the cavity contour to the thick-walled area of the brush holder. Through the circulation of cooling water, it realizes uniform cooling inside and outside the plastic part, shortens the cooling cycle by 15%-20%, and effectively solves the shrinkage and warpage problems of thick-walled parts. During the design stage, CAE mold flow simulation technology is used to predict and optimize the melt flow, pressure distribution and cooling rate, so as to avoid common defects such as bubbles and flash in advance. Meeting the needs of humid bathroom environments, the surface finish of plastic parts molded by the mould can reach Ra0.8μm or less, reducing dirt attachment points, and the tolerance of assembly holes is controlled within ±0.01mm, ensuring precise adaptation between the brush holder and the brush head.

3. Durable Design, Full-Cycle Cost Controllable

Plastic Toilet Brush Holder Mould cavity and core are made of S136 pre-hardened mold steel, which has excellent wear resistance and corrosion resistance after heat treatment above 55HRC and surface nitriding treatment. It can withstand the impurity wear in recycled plastics, and the single maintenance interval is extended to more than 80, 000 cycles. The ejection system adopts gold-plated ejector pins and guide pillars, combined with self-lubricating guide sleeves, to reduce motion friction loss, and the overall service life of the mould exceeds 500, 000 cycles. The standardized mold base structure and vulnerable part design shorten the later maintenance and replacement time to within 4 hours, significantly reducing downtime costs.

4. Experience-Adapted, Strong Scenario Pertinence

Relying on 20 years of experience in R&D of kitchen and bathroom moulds, aiming at the functional needs of toilet brush holders such as anti-water accumulation and easy cleaning, the mould has specially optimized the molding core-pulling mechanism and surface draft angle of the drainage groove to ensure smooth drainage and convenient demoulding of plastic parts. The cavity structure can be quickly adjusted according to customer needs to adapt to personalized designs such as the sealing edge molding of covered brush holders and the installation holes of wall-mounted brush holders, and the sample trial production cycle can be shortened to 7-10 days. A professional technical team is equipped to provide on-site commissioning support, and optimize injection parameters combined with mold trial data to help customers quickly realize mass production ramp-up.

FAQ

Q1: How long does it take to build an injection mold?

Depending on complexity and our tool room load, it can range from 3 to 12weeks.

Q2: Can I modify plastic mold after the first run testing?

We can modify our Plastic Toilet Brush Holder Mould by additional machining, fill-in welding, welding in additional material, or inserting a replacement feature, for a reasonable cost. If the changes are too great, however, producing a new mold may be more cost-effective than reworking the existing one.

Q3: Is the lead time in working days or calendar days?

Lead times are quoted in working days. As per our terms and conditions, quoted lead times commence only after
completion and confirmation of design for manufacturing review and the beginning of actual production.
