If you’re sourcing custom rubber & plastic components for automotive, electrical or forklift equipment, you must have many doubts about samples, lead time, customization, quality and quotation. Based on our official FAQ page (kingtom.com.cn/faq), we sorted out the most frequent questions from global buyers to help you cooperate with us smoothly.

Q1: What products can Kingtom manufacture?

A: We cover full categories of molded & extruded elastomer products, including:

1. Rubber injection molding parts

2. Rubber compression molding parts

3. Rubber extrusion parts (hoses, strips, bellows)

4. Rubber-to-metal bonded components

5. Custom plastic parts

Our items are widely applied in passenger cars, new energy vehicles, industrial electrical equipment and forklift attachments.

Q2: Can I get free samples? What’s the sample rule?

A: Yes, we provide free standard samples for all clients. You only need to cover the international express freight cost. For fully customized new products, we will produce prototype samples after mold development, and the mold fee can be deducted in your bulk order later.

Q3: I don’t have 2D/3D drawings, can you still produce my parts?

A: Absolutely no problem. You can send one physical sample to our factory. Our engineering team will scan, measure and reverse-engineer the item, then make identical products strictly according to your sample structure, size and material hardness.

Q4: How long is the normal delivery time for bulk orders?

A: Our general production cycle ranges from 10 to 30 working days. The exact lead time depends on your order quantity, product complexity and existing factory production schedule. We will confirm a precise schedule after sample approval.

Q5: What details do you need to offer an accurate quotation?

To calculate an exact price for you, please prepare these information:

1. 2D/3D drawings or clear sample photos with full dimension marks

2. Required rubber material and hardness (Shore A)

3. Exact order quantity

4. Extra demands: tolerance standard, surface finish, color

5. Working environment of the product (temperature, oil/water/UV exposure, etc.)

Q6: How does Kingtom guarantee consistent product quality before shipment?

A: We implement strict two-stage quality control:

1. Pre-mass production: All bulk production must be confirmed with signed prototype samples first.

2. Pre-delivery inspection: We complete full dimensional & performance testing, provide formal inspection reports and take clear product photos for your confirmation before arranging shipment.

If you have any other questions not covered above, feel free to send drawings, samples or your project demands to our sales team. We will reply within 24 hours with professional technical support and competitive factory price. Welcome to visit our Xiamen factory for on-site inspection!
